SYSTEMS AND METHODS FOR VERIFYING ADDITIVE MANUFACTURING
WORKFLOWS
PRIORITY CLAIM
This application claims the benefit of the filing date of United States Patent
Application Serial No. 17/454,349, filed November 10, 2021, for "SYSTEMS AND
METHODS FOR VERIFYING ADDITIVE MANUFACTURING WORKFLOWS,"
which claims the benefit under 35 U.S.C. 119(e) of U.S. Provisional Patent
Application
Serial No. 63/188,955, filed May 14, 2021, for "ADDITIVE MANUFACTURING END-
TO-END WORKFLOW PROCESSES," the disclosure of each of which is incorporated
herein in its entirety by this reference.
FIELD
This disclosure relates generally to systems and methods for facilitating,
controlling, and/or verifying manufacturing of products in a distributed
supply chain. More
specifically, disclosed embodiments relate to systems and methods which may
enable
aggregation, access control, revision, version tracking, or any combination of
these for
product designs from different entities; facilitating, controlling, verifying,
or any
combination of these with respect to manufacturing processes for products in
accordance
with the product designs, particularly when additive manufacturing is
employed;
facilitating, controlling, verifying, or any combination of these actions
performed for post-
manufacture processing, delivery, use, maintenance, refurbishment, or any
combination of
these services applied to products; and/or facilitating and/or tailoring
payment for
respective products to different entities having different rights, rates, or
both in a
distributed supply chain.
BACKGROUND
Coordinating manufacture of certain products often involves coordination among
entities. For example, a buyer may place an order requiring materials and
source
components to be provided, manufacturing services to be performed, and post-
manufacture
processing of a product to occur, each of which may involve cooperation among
several
entities. When making products subject to government and/or industry
regulation, and
when a buyer imposes certain quality standards, coordination among the
companies may
also involve certifying source materials and components, calibration of
machines, and
CA 03218321 2023- 11- 7
WO 2022/241457
PCT/US2022/072291
- 2 -
training and certification of personnel involved in manufacturing those
products. When
making products utilizing additive manufacturing (e.g., 3D printing), for
example, the
source material used, name and model of the machine, calibration for the
machine, and
certification of the operator may be required in at least some instances, all
of which may
require coordination and recordkeeping by disparate entities. Additive
manufacturing
techniques facilitate manufacturing complex shapes with relative ease.
Additionally,
additive manufacturing facilitates manufacturing component geometries that
currently
cannot be achieved through certain manufacturing processes such as
conventional
machining processes.
DISCLOSURE
In some embodiments, systems may include a memory device storing instructions
that, when executed by a processor, cause the processor to accept pre-
manufacture
verification of manufacturer capabilities and product precursors for a product
to be
additively manufactured. A blockchain may be updated to associate the pre-
manufacture
verification of manufacturer capabilities and product precursors with an
encrypted, secure
identifier for the product to be additively manufactured utilizing a secure,
distributed
transaction ledger. Discrete packets of operational parameters to enable an
additive
manufacturing device to manufacture the product may be generated. Each packet
may
include operational parameters to enable the additive manufacturing device to
manufacture
a respective portion of the product. Respective packets of operational
parameters may be
encrypted and sent to a network-connected additive manufacturing device. The
respective
packets may be sent for only after receipt of confirmation that at least
another previous
packet is complete and associated operational parameters for the at least
another previous
packet have been deleted. A time from completion of the at least another
previous packet
may be sufficient to ensure that another respective portion of the product to
be
manufactured responsive to execution of a subsequent packet may begin without
interruption in an additive manufacturing process. Inn-manufacture
verification of
operational parameters utilized by the additive manufacturing device when
manufacturing
the product may be accepted. The blockchain may be updated to associate the in-
manufacture verification of the operational parameters with the encrypted,
secure identifier
utilizing the secure, distributed transaction ledger.

In other embodiments, methods may involve accepting pre-manufacture
verification
of manufacturer capabilities and product precursors for a product to be
additively
manufactured. A blockchain may be updated to associate the pre-manufacture
verification
of manufacturer capabilities and product precursors with an encrypted, secure
identifier for
the product to be additively manufactured utilizing a secure, distributed
transaction ledger.
Discrete packets of operational parameters to enable an additive manufacturing
device to
manufacture the product may be generated. Each packet may include operational
parameters to enable the additive manufacturing device to manufacture a
respective portion
of the product. Respective packets of operational parameters may be encrypted
and sent to
a network-connected additive manufacturing device. The respective packets may
be sent
for only after receipt of confirmation that at least another previous packet
is complete and
associated operational parameters for the at least another previous packet
have been
deleted. A time from completion of the at least another previous packet may be
sufficient to
ensure that another respective portion of the product to be manufactured
responsive to
execution of a subsequent packet may begin without interruption in an additive
manufacturing process. Inn-manufacture verification of operational parameters
utilized by
the additive manufacturing device when manufacturing the product may be
accepted. The
blockchain may be updated to associate the in-manufacture verification of the
operational
parameters with the encrypted, secure identifier utilizing the secure,
distributed transaction
ledger.

MODE(S) FOR CARRYING OUT THE INVENTION
The illustrations presented in this disclosure are not meant to be actual
views of any
particular system, act in a method, or component thereof, but are merely
idealized
representations employed to describe illustrative embodiments. Thus, the
drawings are not
necessarily to scale.
Disclosed embodiments relate generally to systems and methods which may enable
aggregation, access control, revision, version tracking, or any combination of
these for
product designs from different entities; facilitating, controlling, verifying,
or any
combination of these with respect to manufacturing processes for products in
accordance
with the product designs, particularly when additive manufacturing is
employed;
facilitating, controlling, verifying, or any combination of these actions
performed for post-
manufacture processing, delivery, use, maintenance, refurbishment, or any
combination of
these services applied to products; and/or facilitating and/or tailoring
payment for
respective products to different entities having different rights, rates, or
both in a
distributed supply chain. More specifically, disclosed are embodiments of
systems,
including software and hardware, for facilitating cooperation among different
entities in a
distributed supply chain for products, which may be used at various phases of
a product
lifecycle, including design, precursor sourcing, manufacturing, post-
processing, payment,
delivery, use, maintenance, and refurbishment, to provide appropriate parties
with control
over, and verification of, at least certain aspects of those phases. Such
control and
verification may reduce risk of theft and copying, may ensure verification of
requested
variables throughout the relevant portions of the process, and may reduce
burdens
associated with verifying product characteristics, quality, accuracy, and
performance.
For a valid product qualification certification, for each part manufactured
there may
be dozens, if not hundreds or thousands, controlled variables requiring
verification. For
CA 03218321 2023- 11- 7
WO 2022/241457

example, variables to be verified may include sourcing and characteristics of
product
precursors, certification of manufacturing device capability to produce within
specified
tolerances, calibration of manufacturing devices, certification of device
operators,
consistency of manufacturing and post-manufacture processes with product
specification,
and product characteristics. Some verifications may be provided by a machine
output, and
some others may be harvested from up-the-supply-chain vendor qualifications
(raw
material for example). The process to collect, verify, store, and make
verifications available
for inspection for each part may typically be accomplished by discrete manual
processes. In
accordance with this disclosure, an encrypted, secure identifier per product
may be
generated and associated with a digital ledger to automatically harvest
qualification and
certification data, directly from Internet-of-things manufacturing devices in
at least some
instances. The resulting digital ledger may be shared with a reviewer (e.g., a
customer, a
government representative) for validation and time stamping. Processes and
materials
provided by up-the-supply-chain vendors may be recorded into the digital
ledger
(optionally with supporting documentation) with restrictive access. Such a
digital ledger
may reduce burdens associated with audits to verify all the quality required
documentations.
Authorization and verification techniques in accordance with this disclosure
may be
implemented in connection with additive manufacturing devices and products
adapted to be
manufactured utilizing additive manufacturing processes. Adaptations to
product designs,
3D part files, and manufacturing specifications to facilitate manufacturing by
additive
manufacturing processes may be subject to intellectual property rights
distinct from any
intellectual property rights attaching to the underlying product, product
design, methods of
manufacturing the product by other techniques, and precursor materials and
components.
For example, such adaptations may implicate patent rights, trade secret
rights, knowhow, or
a combination of these rights, which may or may not be held by the same entity
having
rights in the underlying product, product design, methods of manufacturing,
and precursor
materials and components. Such concerns may be amplified when manufacturing is
decentralized and remotely produced across the globe. Verifying and tracking
the location
and number of reproduction for proper distribution is practically impossible
with a manual
structure. Verification of rights, rights holders, corresponding royalties,
distribution of
product designs and product specifications, and manufacture and distribution
of authorized
products and as the products are being produced within an additive
manufacturing supply

WO 2022/241457
PCT/US2022/072291

chain may be simplified when manufacturing and verifying in accordance with
the
techniques disclosed herein. In some examples, manufacturing and verifying in
accordance
with this disclosure may involve generating discrete data packages that unlock
in sequence
as instructions to the additive manufacturing devices are receiving them
remotely. Such an
approach may enable greater control over the exact numbers of products
produced per
machine, and record required or requested information relevant to the
production (e.g., on a
digital ledger).
The structure and operation of systems in accordance with this disclosure may
incentivize partners in a distributed manufacturing network to adopt and
participate in the
platform. For example, each vendor registered with the platform may receive a
commission
or distribution of each transaction to which a given vendor contributed, or
simply a
commission or distribution of each transaction handled by the platform during
a period of
time in which the given vendor actively participated in the platform. Such an
approach may
enable at least some participants to access technologies that a given
participant is not yet
ready to deploy at scale. For example in the routing of an order in at least
some examples,
information relevant to the order may pass from a (1) Marketplace App to a (2)
Design
Tool App, to a (3) Pre-Qualification app, to a (4) Process monitoring app, to
an (5)
inspection app to a (6) Post Processing app, to a (7) Delivery Tracking app,
to a (8) Digital
warehouse app, to a (9) Category management app, or any combination of these.
Interaction between various apps may be tracked and stored in a (10) digital
ledger, and
printed through a (11) security layer app. While in this example interactions
among eleven
potentially distinct applications may be handled by the platform, only some of
those
applications may be required to implement a given segment of the platform,
with network
partners maintaining others of the applications. Monetization of various
portions of the
platform may be handled through an automatic payment system, for example,
linked to a
given secure identifier for a specific product or manufacturing job.
When implementing systems in accordance with this disclosure in connection
with
additive manufacturing, sustainability advantages may be realized across
product and
material life cycles. For example, additive manufacturing can improve resource
efficiency
and enable closed-loop material flows. These contributions can be monitored,
as well as the
process steps realizing these contributions, and either or both may be
captured in the digital
ledger. The digital ledger may be utilized to calculate automatically a
sustainability index,
potentially in real time, which may assist participants in realizing
sustainability objectives.

In some examples, at least some aspects of contracting, invoicing, payment, or
any
combination of these tasks may be handled by the system. For example, terms
relevant to
manufacturing the product (e.g., features, quality, verification) may be
established when
accepting an order. The system may automatically track and verify fulfillment
of the terms
(e.g., utilizing the one or more smart contracts enabled by the blockchain).
The system may
also automatically handle invoicing, payment, or both responsive to
fulfillment of the
terms, optionally by automatically requesting or effecting payment through a
connected
payment processor (e.g., utilizing an application programming interface
(API)). Such
functionality may beneficially reduce timing during which payment is
outstanding, may
reduce invoicing errors or discrepancies, and improve cash flow and operating
income
efficiency for users.
In some examples, control over a secure, distributed transaction ledger may be
shared between multiple entities participating in the system, potentially
requiring
consensus among the parties for at least some updates to be made to the
secure, distributed
transaction ledger. Consensus control may reduce risks of differing
interpretation, delays,
and miscommunication among the participants. By confirming the qualification
process
utilizing the system, and with a commercial contract in place validating it,
the system may
serve as an alternative to (or replace) regulations or standards
conventionally employed for
qualification, manufacturing, and fulfillment. Such an improved system may
reduce risks
and liabilities for participants in case of operational failures and disputes.
As used herein, the terms "substantially" and "about" in reference to a given
parameter, property, or condition mean and include to a degree that one of
ordinary skill in
the art would understand that the given parameter, property, or condition is
met with a
degree of variance, such as within acceptable manufacturing tolerances. For
example, a
parameter that is substantially or about a specified value may be at least
about 90% the
specified value, at least about 95% the specified value, at least about 99%
the specified
value, or even at least about 99.9% the specified value.
The terms "memory" and "memory device," as used herein, include
microelectronic
devices exhibiting, but not limited to, memory functionality, but exclude
embodiments
encompassing transitory signals. For example, a system on a chip (SoC) is
encompassed in
the meaning of memory device. By way of non-limiting example, memory devices
may
generally include Synchronous Random Access Memory (SRAM), Dynamic RAM

(DRAM), Read-Only Memory (ROM), Flash memory, and the like, unless otherwise
specified.
FIG. 1 is a schematic view of a system 100 for end-to-end verification of
workflow
processes for a product. The system 100 may be at least partially implemented
via software
executable on one or more computer systems in connection with one another over
a
network. The system 100 may include a verification module 102 programmed and
configured to generate, receive, and maintain a secure record of at least some
workflows in
the manufacture of a product. For example, the verification module 102 may be
programmed and configured to receive data from other modules of the system
100, to
maintain and update a secure, distributed transaction ledger with at least
some of the data
received and/or with generated data representative of at least some content of
the received
data, and to control access to the secure, distributed transaction ledger to
ensure the secure,
distributed transaction ledger accurately reflects those portions of the
workflows to be
represented in the secure, distributed transaction ledger.
The verification module 102 may be programmed and configured to generate an
encrypted, secure identifier for each product to be made, the encrypted,
secure identifier
configured to identify the physical product, once made, and enable data
verifying
workflows for manufacturing the product to be collected and verified. In some
examples,
the verification module 102 may also be termed a "security module" or may
include a
security module as a sub-module within the verification module 102. For
example, upon
initiation, and/or receipt, of an order, the verification module 102 may be
programmed and
configured to generate and encrypt an at least substantially unique identifier
to be tied to
each subsequent update in the secure, distributed transaction ledger relevant
to the product.
In some examples, the verification module 102 may query or execute a random
output
generator (e.g., a non-deterministic random number generator, a pseudorandom
number
generator, a pseudorandom number generator seeded by a non-deterministic
random
number generator) to generate a string of bits (e.g., a 128-bit string, a 256-
bit string, a 512-
bit string) to be encrypted and serve as the encrypted, secure identifier. In
other examples,
the verification module 102 may query a database of previously used encrypted,
secure
identifiers (e.g., in a secure, distributed transaction ledger) to retrieve a
last-used encrypted,
secure identifier, decrypt the last-used encrypted, secure identifier, and
alter the last-used
encrypted, secure identifier (e.g., following a pattern, making an incremental
change in a
sequence) to generate a new encrypted, secure identifier for the product. As a
specific,

WO 2022/241457
PCT/US2022/072291
- 9 -
nonlimiting example, the encrypted, secure identifier may include a hash
value, which may
be utilized to chain subsequently generated data relevant to the product
together, forming
an at least substantially unique, inalterable fingerprint for verifying the
data and its
association with the product (e.g., by generating a new, validated fork in a
secure,
distributed transaction ledger).
The encrypted, secure identifier may be utilized to establish and maintain a
secure
record verifying at least some workflows in the life cycle of the product,
from ordering,
through manufacturing, post-processing, fulfillment, delivery, use in the
field, repair,
refurbishment, retirement, or any combination or subcombination of these. For
example,
the verification module 102 may update a blockchain with the encrypted, secure
identifier
to establish a record verifying the workflows for the product utilizing a
secure, distributed
transaction ledger. More specifically, the verification module 102 may
establish a new
block in the blockchain including the encrypted, secure identifier (e.g.,
continuing an
existing fork or starting a new, temporary fork pending validation), the new
block
dedicated to storing data verifying the workflows associated with the product
and chained
to a previous block, may update a not-yet-complete block in the blockchain to
incorporate
the encrypted, secure identifier, or may establish a new blockchain altogether
to
incorporate the encrypted, secure identifier.
In some examples, the encrypted, secure identifier may be or include a token
(e.g., a
non-fungible token) operable in multiple blockchains (e.g., based on the same
or different
cryptographic algorithms). For example, the encrypted, secure identifier may
include a
cross-chain token in accordance with U.S. Patent No. 11,102,003, the
disclosure of which
is incorporated herein in its entirety by this reference. Briefly, the
encrypted, secure
identifier may be generated by invoking a token template defined by a set of
attributes and
control functions representative of a given asset (e.g., the product). When a
token is created
by the template, the token may incorporate the attributes and control
functions of the
template, which may then be deployed across multiple blockchains and
recognized as a
cross-chain token. Configuring the encrypted, secure identifier may facilitate
storage of
different sets of data in different blockchains while enabling the data to be
interlinked to
the encrypted, secure identifier to provide a secure, wholistic record of data
relevant to a
given product.
Encryption and decryption techniques utilized by the verification module 102
may
be adopted, configured, maintained, and utilized to ensure security of files
handled by the
CA 03218321 2023- 11- 7
WO 2022/241457
PCT/US2022/072291
- 10 -
verification module 102. In some examples, the encryption utilized may be
asymmetric.
For example, the verification module 102 may utilize a public key to encrypt
data to be
sent to a given participant in the system 100 (e.g., a customer, a designer, a
manufacturer,
an auditor) or otherwise to be used by a module of the system 100, and a
private key held
solely by that participant and/or module may be required to decrypt the data.
The private
key, and optionally the public key, may be selected and distributed when
screening and
authenticating potential participants for participation in the system 100.
Illustrative
asymmetric encryption techniques usable by the verification module 102 may
include, for
example, Digital Signature Standard (DSS), Elliptic Curve Digital Signature
Algorithm
(ECDSA), Paillier cryptosystem, Rivest¨Shamir¨Adleman (RSA) encryption
algorithm,
etc. In other examples, the encryption utilized by the verification module 102
may be
symmetric. For example, the verification module 102 may utilize a private key
to encrypt
data to be sent to a given participant in the system 100 or otherwise to be
used by a module
of the system, and the same private key may be required to decrypt the data.
The private
keys may be selected and distributed in advance, such as, for example, when
screening and
authenticating potential participants for participation in the system 100.
Illustrative
asymmetric encryption algorithms usable by the verification module 102 may
include, for
example, Twofish, Serpent, AES (Rijndael), Camellia, Salsa20, ChaCha20,
Blowfish,
CASTS, Kuznyechik, RC4, DES, 3DES, Skipjack, Safer, and IDEA.
When data relevant to the product becomes available and the system 100 has
been
configured to record the data, the verification module 102 may accept the data
from
another module, optionally encrypt the data, and update the blockchain to
include the data
in such a way that the data is associated with the encrypted, secure
identifier of the product.
For example, data automatically generated utilizing one of the modules, or
accepted by one
of the modules via user input, may also be received by the verification module
102, the
verification module 102 may optionally encrypt the data, and the verification
module 102
may update a blockchain with the data, and associate the data with, or link
the data to, the
encrypted, secure identifier, to update and maintain the record verifying the
workflows for
the product utilizing the secure, distributed transaction ledger. More
specifically, the
verification module 102 may establish a new block in the blockchain including
the data and
a link or reference to the block including the encrypted, secure identifier,
may update a not-
yet-complete block in the blockchain already including the encrypted, secure
identifier to
incorporate the data, or may update a blockchain dedicated to the product with
the data.

WO 2022/241457
PCT/US2022/072291
-11 -
Updating the blockchain with the data may involve, for example, collecting the
data
in a block, generating a hash to verify the data, and incorporating a hash
from a previous
block in the blockchain to chain the block including the data to the previous
block. When a
node (i.e., a computer system authorized to participate in the blockchain)
generates a block
to be added to the blockchain, consensus from at least one other node on the
blockchain
network may be requested (e.g., required) to validate the block and officially
add it to the
blockchain. For example, when a node operated by a manufacturer generates data
containing verification of operational parameters utilized by a manufacturing
device to
manufacture a product, the verification module 102 may query at least one
other node (and
potentially all other nodes) participating on the blockchain to confirm
acceptance of the
data, potentially prompting review of the data. When acceptance by the
relevant node or
nodes has been received, a hash may be generated and applied to the block
along with the
hash from any preceding block, and the block with the applied hashes may be
distributed to
the nodes to add the block and update the blockchain. Any proposed changes to
(e.g.,
revisions of) the blockchain may likewise request (e.g., require) consensus
from at least
one other node on the blockchain network.
The system 100 may include an ordering module 104 programmed and configured
to accept an order and to transmit data representative of the order to the
verification
module 102 for addition to the blockchain to verify subsequent data relevant
to the product.
For example, the ordering module 104 may be configured to accept input of a
product
identification number, a product name, one or more characteristics to be
exhibited by the
product, one or more performance metrics to be achieved by the product, one or
more
expected uses for the product, or any combination of these to facilitate
ordering of a
suitable product. More specifically, the ordering module 104 may send a web
form to a
client device of a potential customer, the web form containing, for example, a
search bar, a
series of drop-down menus, one or more checkboxes, an array of product names
and/or
images, or any combination of these or other user interface elements to accept
the input for
identifying a suitable product to be ordered. Upon acceptance of a suitable
identification of
the product, the ordering module 104 may send data representative of the
product to the
verification module 102 for generation of the encrypted, secure identifier and
any
associated block or blocks in the blockchain to identify the product and any
other terms
associated with the order.
CA 03218321 2023- 11- 7
WO 2022/241457
PCT/US2022/072291
- 12 -
The ordering module 104 may also be configured to accept input of one or more
terms associated with the order. For example, the ordering module 104 may be
configured
to accept input of a requested or required date for completion of
manufacturing, requested
or required date for completion of post-processing, requested or required
delivery date,
delivery instructions, number of products to be manufactured, requested or
required
precursors for manufacturing the product (e.g., source materials, preformed
components),
requested or required verification data to be received at the verification
module 102 for the
precursors, requested or required manufacturer identity, requested or required
manufacturing processes for manufacturing the product (e.g., with associated
tolerances),
requested or required manufacturing devices for manufacturing the product,
requested or
required verification data to be received at the verification module 102 for
workflows
utilized when manufacturing the product (e.g., manufacturer identify,
manufacturing
device(s) utilized, operational parameters utilized, certifications for device
operators,
calibration for one or more of the manufacturing device(s)), requested or
required post-
manufacture processing to be performed on the product, requested or required
verification
data to be received at the verification module 102 for workflows utilized when
performing
post-manufacture processing on the product (e.g., processes utilized, devices
utilized,
operational parameters utilized), requested or required post-manufacture
product
characteristics (e.g., density, dimensions, adherence to tolerances, surface
roughness),
requested or required verification data to be received at the verification
module 102 for
post-manufacture product characteristics of the product and/or workflows
utilized to
generate the verification data (e.g., processes utilized, devices utilized,
operational
parameters utilized, calibration for one or more of the device(s)).
In some examples, the ordering module 104 may include smart contract
functionality enabled by the blockchain. For example, when an order is
accepted via the
ordering module 104, a smart contract incorporating the required product
characteristics
and any other required terms may be sent from the ordering module 104 to the
verification
module 102. The verification module 102 may update the blockchain to include a
smart
contract incorporating the required product characteristics and any other
required terms.
When the verification module 102 updates the blockchain with verification of
the required
product characteristics and verification of fulfillment of any other required
terms, the smart
contract may execute, triggering payment obligations. In some examples,
execution of the
smart contract may automatically initiate transfer of payment from a customer
account to
CA 03218321 2023- 11- 7
WO 2022/241457
PCT/US2022/072291
- 13 -
one or more service provider accounts. More specifically, execution of the
smart account
may prompt automatic transfer of a blockchain-enabled currency (i.e., a
cryptocurrency)
from a customer account to one or more service provider accounts via the
verification
module 102 interfacing with the blockchain, may prompt automatic transfer of
funds from
a connected account (e.g., a bank account) to one or more service provider
accounts when
preauthorization to withdraw funds has been granted by the customer, or may
prompt
automatic invoicing, requesting payment from the customer, when
preauthorization to
withdraw funds has not been granted by the customer.
In some examples, the system 100 may be configured to accept and verify
intellectual property rights held by one or more parties in a given product
design, and to
ensure any royalties due for a product manufactured in accordance with those
intellectual
property rights are assessed and distributed to appropriate parties. For
example, any
intellectual property rights that a party claims in a product design may be
identified and
verified during a prequalification process for accepting that party's
participation in the
system 100. More specifically, any intellectual property rights, such as, for
example,
patent, trademark, copyright, trade secret, or other intellectual property
rights, covering the
material, shape, configuration, or other features of a product, or covering
methods of
making or using the product, may be verified during prequalification. Any
licensing and
royalties required by the rights-holder may also be prequalified in the system
100. When a
customer wishes to place an order for a product in which other parties have
intellectual
property rights, the ordering module 104 may confirm that the customer has or
can acquire
an appropriate license. For example, the rights-holder(s) may provide licenses
through the
system 100 on fixed terms utilizing smart contracts.
The system 100 and smart contract system may also automatically ensure that
any
royalty payments from the customer are appropriately sent to the rights-holder
upon
fulfillment of the respective portion of the order implicating those rights.
For example, the
system 100 may require up-front payment of royalties for acquiring a license
when placing
an order through the ordering module 104, may require payment of royalties
when
precursor materials or components are acquired, may require payment of
royalties upon
manufacture and/or post-processing of the product, may require payment of
royalties upon
sending or delivery of the product, or may require payment at any combination
or
subcombination of these events.

In some examples, the system 100 may automatically request funds from a
payment
account when royalties are due. For example, when a royalty-triggering event
occurs, the
system may automatically execute at least a royalty-bearing portion of a smart
contract
utilizing the secure, distributed transaction ledger to cause purchaser funds
to be released to
the rights holder(s).
The system 100 may include a digital inventory module 106 programmed and
configured to maintain and access a database storing a digital inventory
including data
sufficient to identify and manufacture respective product designs. For
example, the digital
inventory may include product identifiers (e.g., product numbers), product
names,
marketing information for the products, images and/or renders of products,
recommended
use cases, product designs, 3-dimensional product model files, product
specifications, or
any combination of these data and potentially other data for a product's
lifecycle. In some
examples, the digital inventory may be maintained cooperatively by the digital
inventory
module 106 and the verification module 102 on a blockchain. For example,
verification
data for verifying workflows may be maintained and stored by the verification
module 102
on a first blockchain, and the digital inventory may be maintained and stored
cooperatively
by the verification module 102 and the digital inventory module 106 on a
second, discrete
blockchain separate from the first blockchain. Any interaction of data to take
place between
the first blockchain and the second blockchain may be managed by the
verification
module 102 and/or the digital inventory module 106 to ensure the
confidentiality of data to
be protected from unrestricted public view. Provision of data on any of the
blockchains at
least partially managed by the verification module 102 to any entities not
already
authorized and participating on those blockchains may likewise be managed by
the
verification module 102, particularly when unrestricted, decrypted access is
requested. In
other examples, the digital inventory may be stored in a private, encrypted
database with
access restricted to preauthorized entities (e.g., the digital inventory
module 106).
When interfacing with the ordering module 104, the digital inventory module
106
may be configured to access and provide information sufficient to identify a
product, and to
refrain from accessing or providing confidential information about a product.
For example,
when accepting a product design to be added to the database storing the
digital inventory, a
designer or other owner of a given product design may designate certain
portions of the
data as being freely accessible to the public, certain portions of the data as
being accessible
only to certain identified entities, certain portions of the data as being
accessible only to
CA 03218321 2023- 11- 7
WO 2022/241457
PCT/US2022/072291
- 15 -
manufacturers, certain portions of the data as being accessible only to
network-connected
manufacturing devices and/or control devices for controlling manufacturing
devices, or any
combination of these controls on accessibility. When stored, all the data in
the digital
inventory may be encrypted, and the verification module 102 may selectively
decrypt
certain files in the digital inventory to be provided to the ordering module
104 and
ultimately to a prospective purchaser. For example, the verification module
102 may
selectively decrypt only those files predesignated by any rights holders in
the product as
being authorized for unrestricted public view (e.g., product name, marketing
information,
selected product characteristics, images and/or renders of an exterior of the
product). In
some examples, the data may be re-encrypted by the verification module 102
before
sending to a client device by the ordering module 104. For example, the data
may be re-
encrypted in accordance with a hypertext transfer protocol secure (HTTPS)
standard to
ensure secure, verifiable conununication to the client device.
For any product designs in the digital inventory, the digital inventory module
106
may maintain a version history. For example, when a designer updates, revises,
changes,
edits, or otherwise modifies a product design, a new version of the product
design may be
stored in the digital inventory or made available via a link in the digital
inventory, with
master source files for the product design being stored and secured by a third
party (e.g., a
designer, a manufacturer, a third-party storage provider). More specifically,
each version of
a product design may be tracked with, for example, its own respective
encrypted, secure
product identifier (e.g., a hash) utilized to uniquely identify a given
version of the product
design within a secure, distributed transaction ledger of a blockchain of the
digital
inventory. When implemented utilizing a blockchain, version history of each
product
design on the secure, distributed transaction ledger may automatically be
tracked and
verified by virtue of operation of the blockchain. In some examples, a rights
holder in an
earlier version may restrict access to the earlier version, such that old
versions of product
designs may not be accessible to the ordering module 104 for presentation to a
potential
customer. Thus, a user of the system 100 may be assured that any product
ordered through
the system 100 may be a most up-to-date version or design of a given product.
In some
situations, an old version of a product design may be eliminated from the
digital inventory
altogether (e.g., upon consensus from all nodes and/or participants in the
digital inventory).
In other examples, multiple versions of a given product design may be made
available to
CA 03218321 2023- 11- 7
WO 2022/241457
PCT/US2022/072291
- 16 -
the ordering module 104, enabling a designer or other rights holder to offer
multiple
versions (e.g., for different use cases, at different price points).
In some examples, the system 100 may include a physical inventory module 108
programmed and configured to track and analyze a physical inventory of one or
more
entities participating in the system. For example, the physical inventory
module 108 may
be configured to track and analyze stock of precursor materials, precursor
components,
products, or any combination of these inventory items in a physical inventory
of each
respective entity granting authorization for the physical inventory module 108
of the
system 100 to access that entity's physical inventory. More specifically, the
physical
inventory module 108 may be configured to interface with an existing inventory
tracker
utilized by an entity (e.g., utilizing an API) and receive automatic updates
regarding the
contents of that entity's physical inventory, at least with respect to
selected precursors
and/or products. Data received by the physical inventory module 108 may be
stored, for
example, in a database discrete from any blockchain, or in a third blockchain
discrete from
any other blockchain for product lifecycle verification and or digital
inventory
management. Data receivable by the physical inventory module 108, and storage
policies
for the data, may be tailored to a user's preferences.
When an entity connects to the ordering module 104, the physical inventory
module 108 may optionally provide information regarding the current contents
of that
entity's physical inventory. For example, the physical inventory module 108
may filter
contents of the entity's physical inventory to send the names and current
stock of similar
products to those searched and/or viewed by the entity utilizing the ordering
module 104.
In some examples, the physical inventory module 108 may proactively analyze an
entity's
physical inventory and a rate of depletion of the entity's physical inventory.
For example,
the physical inventory module 108 may send a notification to a user of a
current quantity of
a given product and an estimated time at which stock is predicted to fall
below a
predetermined minimum with sufficient lead time for the user to place an order
for one or
more products utilizing the ordering module 104 and for those products to be
manufactured
and delivered before stock falls below the predetermined minimum. As another
example,
the physical inventory module 108 may automatically place an order with the
ordering
module 104 for a given product at a predetermined interval before a predicted
depletion of
stock of the product in the physical inventory, such as, for example, timed so
that the
CA 03218321 2023- 11- 7
WO 2022/241457
PCT/US2022/072291
- 17 -
product will likely be manufactured and delivered before stock falls below the
predetermined minimum.
In some examples, the system 100 may include a design selection assistance
module 110 programmed and configured to provide recommendations to a
prospective
customer searching within the ordering module 104 of product designs,
specifications,
and/or materials that may potentially suit the prospective customer's use
case. When the
ordering module 104 receives inputs in search of a product in the digital
inventory,
particularly when those inputs do not identify a specific product, the design
selection
assistance module 110 may be programmed and configured to analyze those
inputs, search
the digital inventory for product designs, or search in a materials database
for materials
and/or a specification database for specifications, most closely matching the
inputs, and
provide one or more closest matching products, materials, and/or
specifications for output
as potential recommended product designs. For example, receipt of inputs
representing
expected uses for a product, absent corresponding identification of a desired
product for
performing the expected uses, may trigger the design selection assistance
module 110 to
search the digital inventory for product designs having the closest
recommended use cases,
product designs having the closest verified in-field performance, or both, and
output a
subset (e.g., a list with a predefined number of results, a list with a number
of results
corresponding to an available area on a display of a client device) of the
digital inventory to
recommend those product designs for potential selection. In some examples, the
design
selection assistance module 110 may include an artificial-intelligence
assisted, machine
learning algorithm, enabling the design selection assistance module 110 to
adaptively
provide recommendations based on a wholistic analysis of the inputs as well as
other
potentially relevant data (e.g., order history, popularity rankings of product
designs).
Upon acceptance of an order utilizing the ordering module 104, the
verification
module 102 may generate the encrypted, secure identifier for the product to be
manufactured and update the blockchain for verifying workflows relevant to the
lifecycle
of the product to include the encrypted, secure identifier, sufficient
information to identify
the product and version, and any other terms required or requested for
fulfillment in
connection with manufacturing, post-processing, and delivery of the product.
For example,
the verification module 102 may generate a "digital twin" of the product to be
manufactured, including the encrypted, secure identifier, sufficient
information to identify
the product, sufficient information to facilitate manufacturing the product,
and any other
CA 03218321 2023- 11- 7
WO 2022/241457
PCT/US2022/072291
- 18 -
terms in the order, and store the digital twin in the secure, distributed
transaction ledger
with the encrypted, secure identifier. Any smart contract to be executed in
connection with
the product may also be stored on the blockchain in connection with the
digital twin.
After acceptance of the order, a manufacturing module 112 of the system 100
may
coordinate manufacturing of the product or products in accordance with the
terms set forth
in the order. In some examples, the system 100 may be vertically integrated,
with a single
entity accepting the order from the ordering module 104, manufacturing the
product, and
fulfilling the order. In other examples, the system 100 may be at least
partially
decentralized, with the ordering module 104 and the manufacturing module 112
coordinating fulfillment of a given order or orders by multiple entities.
Regardless,
manufacturing instructions including at least precursors required to begin
manufacturing,
manufacturing devices to be used, the product, and any other terms necessary
for the
manufacturer to know up-front when preparing to manufacture the product (e.g.,
delivery
date, verification data required) may be sent to the entity or entities
coordinating fulfillment
of the order. To protect details of the product designs from inadvertent
disclosure, all
transmission of data for manufacturing the product by the manufacturing module
112 to a
client device may be encrypted. For example, the manufacturer(s) may be
required to
utilize a respective private key established when setting the system 100 in
place to decrypt
the information enabling the manufacturer(s) to make preparations to
manufacture the
product.
Prior to receiving any further instructions for manufacturing the product from
the
manufacturing module 112, any manufacturer may be required to send
verification of
predetermined preliminary qualifications to the verification module 102 in
some examples.
For example, a manufacturer may be required to send, and the system 100 may
require
receipt of, verification that precursor materials to be used are in possession
of the
manufacturer, that precursor components to be used are in possession of the
manufacturer,
that manufacturing devices having required capabilities are in possession of
the
manufacturer, the manufacturing devices to be used have been calibrated in
accordance
with customer and/or industry standards, operators have any required
certifications and/or
training, or any combination or subcombination of these preliminary
qualifications.
Accepting such preliminary qualifications for verification may involve, for
example,
receiving an upload of another encrypted, secure identifier associated with a
prequalifi cati on portfolio of the manufacturer stored in a database of
preverified
CA 03218321 2023- 11- 7
WO 2022/241457
PCT/US2022/072291
- 19 -
manufacturer qualifications and/or capabilities (e.g., another blockchain),
which may be
accessible to a recipient of the encrypted, secure identifier through the
verification
module 102.
In some examples, updating the blockchain, particularly to add a new block to
the
blockchain, may require acceptance of the relevant data to be by consensus of
at least some
of the other parties already qualified within the system 100. For example, the
system 100
may require acceptance of the relevant data by consensus of each party hosting
a node of
the blockchain. As another example, the system 100 may require acceptance of
the relevant
data by consensus of each party participating in the blockchain.
As another example, accepting preliminary qualifications may involve receiving
verification of manufacture of a witness mass including the same material(s)
and optionally
the same material composition as at least a portion of the product is to be
manufactured
from. To tie the witness mass to the encrypted, secure identifier of the
product, one or more
physical characteristics of the witness mass may be altered, and the
alteration stored in the
blockchain in connection with the encrypted, secure identifier to indicate
that detection of
the identified physical characteristics in the witness mass is representative
of the materials
and manufacturing processes to be used for the product. More specifically, the
manufacturing module 112 may instruct a network-connected additive
manufacturing
device to control one or more operational parameters (e.g., material feed
rate, material
dispenser position and/or movement rate, position and/or intensity of applied
heat) to
produce a randomized variation in one or more product characteristics (e.g.,
density,
surface roughness, distribution of different materials) in one or more
portions of the
witness mass (e.g., in a layer thereof, on an exterior surface thereof). The
verification
module 102 may encrypt and store data representative of the randomized
variation in the
blockchain such that the data representative of the randomized variation is
associated with
the encrypted, secure identifier of the product. An entity wishing to audit
the workflow for
the product may inspect the witness mass to detect the randomized variation,
send the
randomized variation to the verification module 102, and receive from the
verification
module 102 an indication of the encrypted, secure identifier associated with
the
randomized variation and the product.
As yet another example, accepting preliminary qualifications may involve
receiving
timestamped images of manufacturing devices, calibration certificates,
training and/or
qualification certificates for operators, or any combination or subcombination
of these
CA 03218321 2023- 11- 7
WO 2022/241457
PCT/US2022/072291
- 20 -
preliminary qualifications. The timestamped images may be received at the
verification
module 102, encrypted, and stored in the blockchain in connection with the
encrypted,
secure identifier for the product.
In some examples, the verification of precursors to manufacture the product
may
include data regarding the sustainability of materials and components to be
used when
making the product. For example, the verification module 102 may request or
require
receipt of indications of the environmental impact of sourcing the precursors
and their
sustainability. More specifically, the verification module 102 may request or
require receipt
of indications of, for example, whether the precursors a recycled from a
previous product, a
measure of green-house gas emissions from sourcing the precursors, an
indication whether
the precursors are from a renewable source, an indication how the precursors
may be
reused or recycled upon retirement of the product, or any combination or
subcombination
of these or other indications of sustainability. Upon receipt, the
verification module 102
may update the blockchain to associate received indications of sustainability
with the
encrypted, secure identifier. In some examples, the verification module 102
may also
calculate an impact the verified indications of sustainability have on an
entity's target
environmental and sustainability goal, such as, for example, by recalculating
a
sustainability score of the entity (e.g., by rating whether the entity is on
track to, predicted
to be 10% or closer off track from, or predicted to be more than 10% off track
from
meeting sustainability targets) based on the added indications.
After acceptance of any verification for any preliminary qualifications, the
manufacturing module 112 may send further instructions for manufacturing the
product. In
some examples where the manufacturing device(s) to be used may not be
automatically
controlled, the verification module 102 may send an encrypted file including a
specification, tolerances, and any other manufacturing instructions to be
decrypted by the
manufacturer utilizing a private key. The encrypted file may be decryptable by
the
manufacturer and may contain sufficient information for the manufacturer to
manufacture
the product in accordance with requirements and preferences in the order.
In other examples where the manufacturing device(s) to be used may be
automatically controlled, the verification module 102 may generate or access
pre-generated
instructions configured to cause the manufacturing device(s) to automatically
manufacture
the product, encrypt the instructions, and send the encrypted instructions to
the
manufacturing device(s) for decryption and use to automatically manufacture
the product
CA 03218321 2023- 11- 7
WO 2022/241457
PCT/US2022/072291
- 21 -
from the precursors utilizing the manufacturing device(s). For example, the
verification
module 102 may determine a rate at which a manufacturing device (e.g., an
additive
manufacturing device) may be capable of manufacturing the product, may encrypt
and send
a packet of instructions to the manufacturing device, the packet containing
only so many
instructions to enable the manufacturing device to manufacture a portion of
the product
upon decryption of the packet of instructions utilizing the manufacturer's
private key. As
the manufacturing device manufactures the product, the manufacturing module
112 may
encrypt and send another packet of instructions to the manufacturing device,
the other
packet containing instructions to enable the manufacturing device to
manufacture a
subsequent portion of the product upon decryption of the packet of
instructions utilizing the
manufacturer's private key. The respective packets may contain instructions so
that a
preceding packet may be fully executed, manufacturing the relevant portion of
the product,
deleted, and deletion confirmed to the verification module 102 while the
manufacturing
device executes the instructions in a subsequent packet. The respective
packets may also
contain instructions so that manufacturing processes are not interrupted
following deletion
of the preceding packet and before a still subsequent packet can be received
(e.g., layer by
layer when a given packet includes sufficient instructions to manufacture an
associated
layer). With such a process, manufacturing may be efficiently and
expeditiously completed,
though the manufacturer may never be granted access to a full, unencrypted set
of
instructions for manufacturing the product.
In some examples, the packets of instructions may be generated and transmitted
by
granting the manufacturer (or the manufacturing device) temporary access to
one or more
private keys of a blockchain storing the packets of instructions. The
blockchain may
automatically record access to, transmission of, and deletion of copies of the
instructions
by a client device, ensuring that the manufacturer's access and use of the
data is in
accordance with terms in the order and any terms set by a designer or other
rights holder in
the product design (and providing an immutable record of any improper access,
use, and
copying).
To tie the product to the encrypted, secure identifier for the product, one or
more
physical characteristics of the product may be altered or the inevitable,
naturally occurring,
random variations in characteristics of the product (e.g., within
specification, within
tolerance) may be detected, and the alteration or variation stored in the
blockchain in
connection with the encrypted, secure identifier to indicate that detection of
the identified
CA 03218321 2023- 11- 7
WO 2022/241457
PCT/US2022/072291
- 22 -
physical characteristics in the product is representative of the materials and
manufacturing
processes used when manufacturing the product. More specifically, the
manufacturing
module 112 may instruct a network-connected additive manufacturing device to
control
one or more operational parameters (e.g., material feed rate, material
dispenser position
and/or movement rate, position and/or intensity of applied heat) to produce a
randomized
variation in one or more product characteristics (e.g., density, surface
roughness,
distribution of different materials) in one or more portions of the product
(e.g., in a layer
thereof, on an exterior surface thereof). The randomized produced variation
may also be a
consequence of normal statistical errors and deviations from exact values
within
manufacturing tolerances. The verification module 102 may encrypt and store
data
representative of the randomized variation in the blockchain such that the
data
representative of the randomized variation is associated with the encrypted,
secure
identifier for die product. An entity wishing to audit the workflow for the
product may
inspect the product to detect the randomized variation, send the randomized
variation to the
verification module 102, and receive from the verification module 102 an
indication of the
encrypted, secure identifier associated with the randomized variation and the
product. In
some examples, the alteration to the product may match a corresponding
alteration in a
witness mass produced when preparing to make or when making the product.
In some examples, the verification module 102 may receive verification of
operational parameters of a manufacturing device while the product is being
made. For
example, a network-connected manufacturing device (e.g., an additive
manufacturing
device) may send a record of operational parameters utilized when
manufacturing the
product to the verification module 102 in real time. The verification module
102 may
record all the operational parameters utilized by the manufacturing device,
providing real-
time updates to the secure, distributed transaction ledger and associating
those updates with
the encrypted, secure identifier for the product, in some examples. Any record
of actual
operational parameters utilized may be encrypted to reduce the risk that a
product and any
methods of making that product may be reverse-engineered utilizing the record.
In other
examples, the verification module 102 may compare a completed record of the
operational
parameters utilized by the manufacturing device to a product specification,
including any
tolerances, and update the secure, distributed transaction ledger with an
indication that
manufacturing was within specification or was outside specification.
CA 03218321 2023- 11- 7
WO 2022/241457
PCT/US2022/072291
- 23 -
In some examples, the verification of operational parameters of manufacturing
devices while the product is being made may include data regarding the
sustainability of
manufacturing processes and materials used when making the product. For
example, the
verification module 102 may request or require receipt of indications of the
environmental
impact of manufacturing the precursors into the product and the sustainability
of
manufacturing processes utilized to produce the product. More specifically,
the verification
module 102 may request or require receipt of indications of, for example,
energy expended
in manufacturing the product, source of the energy expended in manufacturing
the product,
a measure of green-house gas emissions from energy expended in manufacturing
the
product, identification of any lubricants and/or coolants used when
manufacturing the
product, whether the lubricants and/or coolants used when manufacturing the
product are
reusable, recyclable, and/or biodegradable, or any combination or
subcombination of these
indications of sustainability. Upon receipt, the verification module 102 may
update the
blockchain to associate received indications of sustainability with the
encrypted, secure
identifier. In some examples, the verification module 102 may also calculate
an impact the
verified indications of sustainability have on an entity's target
environmental and
sustainability goal, such as, for example, by recalculating a sustainability
score of the entity
(e.g., by rating whether the entity is on track to, predicted to be 10% or
closer off track
from, or predicted to be more than 10% off track from meeting sustainability
targets) based
on the added indications.
In some examples, the verification module 102 may receive in-process
verification
of characteristics of the product during manufacturing. For example, data from
one or more
sensors positioned and oriented to detect characteristics of the product
during
manufacturing may be received at the verification module 102, and the
verification
module 102 may update the blockchain with the data or information
representative of the
data. The sensors may include image sensors, thermal sensors, acoustic sensors
(e.g.,
ultrasonic sensors), distance sensors, or other sensors known in the art for
monitoring a
manufacturing process. Data received from the sensors may be representative
of, for
example, still images of an intermediate product in process of manufacturing
the product,
video of a complete process of manufacturing the product, density, dimensions,
peak
temperature (e.g., proximate to application of heat to a precursor material in
an additive
manufacturing device configured as a selective laser sintering device), or
other product
characteristics. The verification module 102 may record all the data
representative of the
CA 03218321 2023- 11- 7
WO 2022/241457
PCT/US2022/072291
- 24 -
product characteristics from the sensors, providing real-time updates to the
secure,
distributed transaction ledger and associating those updates with the
encrypted, secure
identifier for the product, in some examples. In other examples, the
verification
module 102 may compare a completed record of the product characteristics from
the
sensors to a product specification, including any tolerances, and update the
secure,
distributed transaction ledger with an indication that product characteristics
are within
specification or are outside specification.
When manufacturing is verified as being complete, and the record of
manufacturing
and/or product characteristics is not within specification, the verification
module 102 may
at least temporarily suspend any further progress toward fulfillment of the
order. In some
examples, the verification module 102 may send a request for the entity that
placed the
order to accept or reject the product, given the known deviations from the
specification.
When receiving acceptance of the product despite the deviations, the
manufacturing
module 112 and/or an order fulfillment module 114 may proceed toward
fulfillment of the
order. When receiving rejection of the product because of the deviations, the
ordering
module 104 may cancel the order or the manufacturing module 112 may coordinate
re-
manufacturing of the item in accordance with the specification, potentially
utilizing a
different manufacturing device and/or a different manufacturer altogether.
When
coordinating re-manufacturing of the product utilizing the same manufacturer,
the
verification module 102 may provide an indication of the reasons the product
was rejected
(e.g., a list of product characteristics outside specification, a disclosure
of values for the
product characteristics as compared to the specification) and optionally
recommendations
for additional process controls that may be utilized to increase the
likelihood that
subsequent manufacturing efforts will result in a product within
specification.
In some examples, the verification module 102 may compare the deviations from
the specification to sets of predefined thresholds to automatically determine
whether to
accept or reject the product. For example, the ordering module 104 may accept
one or more
thresholds outside a specification for the product design of the product,
within which the
customer will accept deviations, and outside which the customer will not
accept deviations.
When the actual deviations are outside the specification and within the
threshold(s), the
verification module 102 may automatically record acceptance of the product in
the
blockchain, consistent with the order, and the manufacturing module 112 may
proceed
toward fulfillment. When the actual deviations are outside the specification
and outside one

or more of the threshold(s), the verification module 102 may automatically
record rejection
of the product in the blockchain, consistent with the order, and the ordering
module 104
may cancel the order or the manufacturing module 112 may coordinate re-
manufacturing of
the product.
In some examples, the manufacturing module 112 may also coordinate any post-
processing of the product to be performed in accordance with the product
design and/or the
order. For example, when the manufacturer has preapproved equipment and
capabilities to
perform the relevant post-processing (e.g., heat treatment, surface treatment,
assembly), the
manufacturing module 112 may coordinate post-processing in a manner similar to
coordination of manufacturing. More specifically, the manufacturing module 112
may send
requests for verification for any precursor materials and post-processor
capabilities, the
verification module 102 may update the blockchain with received verification,
the
manufacturing module 112 and verification module 102 may cooperatively send
instructions and request/receive verification of operational parameters for
post-processing
of the product, and the verification module 102 may request/receive, in-
process verification
of product characteristics during post-processing. The verification module 102
may update
the blockchain with all data received or with an indication that the data
passed or did not
pass comparisons against the specification to associate the verification with
the encrypted,
secure identifier in the secure, distributed transaction ledger.
In some examples, the verification module 102 may receive data representative
of
final, post-manufacture (and after post-processing) characteristics of the
product. For
example, data from one or more sensors positioned and oriented to detect
characteristics of
the product following completion of all instructions from the manufacturing
module 112
may be received at the verification module 102, and the verification module
102 may
update the blockchain with the data or information representative of the data.
The sensors
may include, for example, image sensors, thermal sensors, acoustic sensors
(e.g., ultrasonic
sensors), distance sensors, or other sensors known in the art for monitoring a
manufacturing process. As a specific, nonlimiting example, the product may be
scanned by
a computed tomography (CT) scanner. Data received from the sensors may be
representative of, for example, still images of the final product, CT scanner
data, density,
dimensions, surface roughness, material composition, or other product
characteristics. The
verification module 102 may record all the data representative of the final
product
characteristics from the sensors, providing updates to the secure, distributed
transaction

WO 2022/241457
PCT/US2022/072291

ledger and associating those updates with the encrypted, secure identifier for
the product, in
some examples. In other examples, the verification module 102 may compare a
completed
record of the product characteristics from the sensors to a product
specification, including
any tolerances, and update the secure, distributed transaction ledger with an
indication that
product characteristics are within specification or are outside specification.
In some examples, the verification of data representative of post-manufacture
processing of the product may include data regarding the sustainability of
processes and
materials used when performing post-manufacture processing on the product. For
example,
the verification module 102 may request or require receipt of indications of
the
environmental impact of post-processing performed on the product and the
sustainability of
post-manufacturing processes utilized for post-processing. More specifically,
the
verification module 102 may request or require receipt of indications of, for
example,
energy expended in post-processing the product, source of the energy expended
in post-
processing the product, a measure of green-house gas emissions from energy
expended in
post-processing the product, identification of any lubricants and/or coolants
used when
post-processing the product, whether the lubricants and/or coolants used when
post-
processing the product are reusable, recyclable, and/or biodegradable, or any
combination
or subcombination of these or other indications of sustainability. Upon
receipt, the
verification module 102 may update the blockchain to associate received
indications of
sustainability with the encrypted, secure identifier. In some examples, the
verification
module 102 may also calculate an impact the verified indications of
sustainability have on
an entity's target environmental and sustainability goal, such as, for
example, by
recalculating a sustainability score of the entity (e.g., by rating whether
the entity is on
track to, predicted to be 10% or closer off track from, or predicted to be
more than 10% off
track from meeting sustainability targets) based on the added indications.
When post-processing is verified as being complete, and the record of post-
processing and/or final product characteristics is not within specification,
the verification
module 102 may at least temporarily suspend any further progress toward
fulfillment of the
order. In some examples, the verification module 102 may send a request for
the entity that
placed the order to accept or reject the product, given the known deviations
from the
specification. When receiving acceptance of the product despite the
deviations, the order
fulfillment module 114 may proceed toward fulfillment of the order. When
receiving
rejection of the product because of the deviations, the ordering module 104
may cancel the
CA 03218321 2023- 11- 7
WO 2022/241457
PCT/US2022/072291
- 27 -
order or the manufacturing module 112 may coordinate re-manufacturing of the
item in
accordance with the specification, potentially utilizing a different
manufacturing device
and/or a different manufacturer altogether. When coordinating re-manufacturing
of the
product utilizing the same manufacturer, the verification module 102 may
provide an
indication of the reasons the product was rejected (e.g., a list of product
characteristics
outside specification, a disclosure of values for the product characteristics
as compared to
the specification) and optionally recommendations for additional process
controls that may
be utilized to increase the likelihood that subsequent manufacturing efforts
will result in a
product within specification.
In some examples, the verification module 102 may compare the deviations from
the specification to sets of predefined thresholds to automatically determine
whether to
accept or reject the final product. For example, the ordering module 104 may
accept one or
more thresholds outside a specification for the product design of the product,
within which
the customer will accept deviations, and outside which the customer will not
accept
deviations. When the actual deviations are outside the specification and
within the
threshold(s), the verification module 102 may automatically record acceptance
of the
product in the blockchain, consistent with the order, and the system 100 may
proceed
toward fulfillment. When the actual deviations are outside the specification
and outside one
or more of the threshold(s), the verification module 102 may automatically
record rejection
of the product in the blockchain, consistent with the order, and the ordering
module 104
may cancel the order or the manufacturing module 112 may coordinate re-
manufacturing of
the product.
When the product has been manufactured and acceptance of the product has been
confirmed by the verification module 102, an order fulfillment module 114 may
coordinate
fulfillment of the order with the product. For example, the order fulfillment
module 114
may send a communication to a customer when manufacturing and post-processing
for a
product ordered by the customer are complete and the product has been approved
for
delivery. in some examples, the order fulfillment module 114 may be configured
to track
delivery of the product to the customer, such as, for example, by receiving
updates on
delivery status from a product delivery service provider (e.g., utilizing an
API) and making
the updates available to the customer. In some examples, the verification
module 102 may
be programmed and configured to update the blockchain with information
regarding order
fulfillment in association with the encrypted, secure identifier.
CA 03218321 2023- 11- 7
WO 2022/241457
PCT/US2022/072291
- 28 -
In some examples, the verification of fulfillment and delivery may include
data
regarding the sustainability of fulfillment and delivery used when fulfilling
the order. For
example, the verification module 102 may request or require receipt of
indications of the
environmental impact of packaging and delivering the product to the customer.
More
specifically, the verification module 102 may request or require receipt of
indications of,
for example, materials and material quantities used for packaging the product,
whether the
materials used to package the product are reusable, recyclable, and/or
biodegradable,
energy expended in delivering the product, source of the energy expended in
delivering the
product, a measure of green-house gas emissions from energy expended in
delivering the
product, or any combination or subcombination of these or other indications of
sustainability. Upon receipt, the verification module 102 may update the
blockchain to
associate received indications of sustainability with the encrypted, secure
identifier. In
some examples, the verification module 102 may also calculate an impact the
verified
indications of sustainability have on an entity's target environmental and
sustainability
goal, such as, for example, by recalculating a sustainability score of the
entity (e.g., by
rating whether the entity is on track to, predicted to be 10% or closer off
track from, or
predicted to be more than 10% off track from meeting sustainability targets)
based on the
added indications.
In some examples, the system 100 may include a use and wear input module 116
programmed and configured to receive data indicative of in-field use and/or
post-use wear
during the useful life of the product. For example, the use and wear input
module 116 may
be programmed and configured to receive data regarding usage of the product in
the field
(e.g., time in the field, operational parameters utilized when using the
product, location of
use, components and/or systems utilized in connection with the product,
entities and/or
persons operating the product), such as by receiving the data from a connected
customer
system utilizing an API. In some examples, a network-connected in-field device
(e.g., a
control system for controlling operation of the product in the field) may send
a record of
operational parameters utilized when operating the product to the verification
module 102
in real time. The verification module 102 may record all the operational
parameters utilized
by the in-field device, providing real-time updates to the secure, distributed
transaction
ledger and associating those updates with the encrypted, secure identifier for
the product, in
some examples.
CA 03218321 2023- 11- 7
WO 2022/241457
PCT/US2022/072291
- 29 -
As another example, the use and wear input module 116 may be programmed and
configured to receive data representative of wear and degradation of the
product due to in-
field use. Such data may include, for example, changes in dimensions, changes
in surface
roughness, changes in material composition (particularly at exposed surfaces),
or other
indicators of wear and degradation of the product. The data may be produced
utilizing, for
example, one or more sensors positioned and oriented to detect characteristics
of the
product following completion of an in-field deployment and may be received at
the
verification module 102. The verification module 102 may update the blockchain
with the
data or information representative of the data. The sensors may include, for
example, image
sensors, thermal sensors, acoustic sensors (e.g., ultrasonic sensors),
distance sensors, or
other sensors known in the art for monitoring a manufacturing process. As a
specific,
nonlimiting example, the product may be scanned by a computed tomography (CT)
scanner. Data received from the sensors may be representative of, for example,
still images
of the used product, CT scanner data, density, dimensions, surface roughness,
material
composition, or other product characteristics. The verification module 102 may
record all
the data representative of the used product characteristics from the sensors,
providing
updates to the secure, distributed transaction ledger and associating those
updates with the
encrypted, secure identifier for the product, in some examples.
The system 100 may include a repair and refurbishment module 118 in some
examples, the repair and refurbishment module 118 programmed and configured to
coordinate and verify any efforts to repair, maintain, and refurbish the
product following
in-field use. For example, when a record of the use and/or wear of the product
approaches,
reaches, or exceeds a predefined threshold (e.g., set by a product designer or
other rights
holder in the product design for the product), the repair and refurbishment
module 118 may
send a recommendation to a client device of the customer to repair, maintain,
refurbish,
retire, or otherwise address the use and/or wear on the product (e.g., by
backfilling voids,
re-performing heat treatment, replacing components). In some examples, the
repair and
refurbishment module 118 may coordinate repair, maintenance, refurbishment,
retirement,
or other actions to be taken in connection with the product following use. For
example, the
repair and refurbishment module 118 may facilitate contact between the owner
of the
product and the manufacturer or a third-party service provider to ensure that
appropriate
repair, maintenance, refurbishment, retirement, or other actions to be taken
in connection
with the product following use is provided.
CA 03218321 2023- 11- 7
WO 2022/241457
PCT/US2022/072291
- 30 -
The verification module 102 may receive verification of any repair,
maintenance,
refurbishment, retirement, or other actions to be taken in connection with the
product
following use and may update the blockchain to incorporate the verification in
a manner
linked to the encrypted, secure identifier to track the lifecycle of the
product. For example,
data verifying repair, maintenance, and/or refurbishment may be produced
utilizing, for
example, one or more sensors positioned and oriented to detect characteristics
of the
product during and/or following completion of such repair, maintenance, and/or
refurbishment and may be received at the verification module 102. The
verification
module 102 may update the blockchain with the data or information
representative of the
data. The sensors may include, for example, image sensors, thermal sensors,
acoustic
sensors (e.g., ultrasonic sensors), distance sensors, or other sensors known
in the art for
monitoring a repair, maintenance, and/or refurbishment process. As a specific,
nonlimiting
example, the product may be scanned (or re-scanned) by a computed tomography
(CT)
scanner. Data received from the sensors may be representative of, for example,
still images
of the used product, CT scanner data, density, dimensions, surface roughness,
material
composition, or other product characteristics. The verification module 102 may
record all
the data representative of the repaired, maintained, and/or refurbished
product
characteristics from the sensors, providing updates to the secure, distributed
transaction
ledger and associating those updates with the encrypted, secure identifier for
the product, in
some examples. Retirement of the product may be validated by receiving an
indication
from the owner or other possessor that they no longer intend to use the
product, and the
verification module 102 updating the blockchain to show that the lifecycle of
the product is
complete by associating the indication of retirement with the encrypted,
secure identifier in
the secure, distributed transaction ledger.
When a product is retired, the system 100 may facilitate reordering a
replacement.
For example, upon receipt of an indication that the product has been retired,
the digital
inventory module 106 may search the digital inventory to determine whether the
same
product or an updated version of the product is available. The ordering module
104 may
send a request for confirmation regarding a potential reorder of the product
or updated
version of the product to the owner or other possessor of the retired product.
Alternatively,
the ordering module 104 may automatically reorder the product or an updated
version of
the product, send confirmation of the reorder to the owner or other possessor
of the retired
product, and proceed toward fulfillment

In some examples, users of the system 100 may be subjected to a
prequalification
process before being authorized to access and utilize one or more modules of
the
system 100. For example, an entity may confirm with an administrator of the
system the
functionality of the system 100 the entity anticipates using, the entity's
identity and
authorization of those persons and devices operating with the system 100 to
act on behalf
of the entity, the entity's willingness to comply with any requirements of the
system 100
(e.g., connectivity, maintenance of security, commitment to supply reliable
information,
ongoing participation), the entity's capabilities (e.g., licensing and
certification of users,
operators, and/or technicians, machinery owned, client devices and controls
therefor,
databases and controls therefor), or any combination or subcombination of
these or other
prequalification metrics. In some examples, authorization for a new entity to
participate in
the system 100 may require consensus among at least some of the existing
participants in
the system. In other examples, new entities may be prequalified so long as
they meet
prerequisite standards established within the system 100, or in response to
unilateral
administrator approval.
Upon prequalification, an entity may be registered within the system 100, any
requisite public or private keys to encrypt data to be received by the system
100 may be
sent to the entity, any requisite private keys to decrypt data sent from the
system 100 may
be sent to the entity, software to enable authorized client devices of the
entity to interface
with the system 100 may be sent for installation, and any other actions to
facilitate entity
participation in the system 100 may be undertaken. For example, information
confirming
rights to a product design, information sufficient for a potential purchaser
to identify the
product design when ordering, and information sufficient to manufacture the
product
design, or any combination or subcombination of these and any other requested
or required
information relevant to a product design, its designer, or its current owner
may be received
from a designer or other rights holder in a product design. The verification
module 102 and
the digital inventory module 106 may cooperatively receive and store the
product design in
a designated database, such as a blockchain dedicated to product designs or a
blockchain
dedicated to product designs by the designer or other rights holder, with
access restrictions
put in place as discussed previously herein.
As another example, a listing of manufacturing devices in service,
identification of
how the manufacturing devices are operated (e.g., manual, computer controlled,
fully
automatic, integrated system) and whether the manufacturing devices are
network-
CA 03218321 2023- 11- 7
WO 2022/241457
PCT/US2022/072291
- 32 -
connectable, information confirming licensing and certifications for operators
of the
manufacturing devices, or any combination or subcombination of these and any
other
requested or required information relevant to a manufacturer and its
capabilities may be
received from a designer or other rights holder in a product design. If
adequate control and
security software is not currently deployed across the manufacturer's devices,
The
verification module 102 and the digital inventory module 106 may cooperatively
receive
and store the manufacturer capabilities, and confirmation of installation of
control and
security software, in a designated database, such as a blockchain dedicated to
coordinating
manufacturers for given orders or a blockchain dedicated to a specific
manufacturer, with
access restrictions put in place as discussed previously herein.
Other entities that may be prequalified for participation in the system may
include,
for example, customers, suppliers of precursor materials and/or components,
post-
processors (e.g., providers of surface treatments, heat treatments, assembly,
system
integration), delivery service providers, in-field operators, providers of
post-use services
(e.g., repair, maintenance, refurbishment), providers of post-retirement
services (e.g.,
recyclers, component salvagers, material reprocessors, providers of disposal
services),
auditors, regulators, or any combination or subcombination of these or other
entities
involved in the design, manufacture, delivery, and use of a product.
In some examples, systems 100 in accordance with this disclosure may
facilitate
secure, reliable manufacturing of products with a verified record of relevant
data for the
product from order, through manufacturing and fulfillment, and optionally
throughout an
entire lifecycle of the product. For example, the manufacturing module 112 of
the
system 100 may be configured to facilitate manufacturing by a decentralized
network of
manufacturers, enabling concurrent mass production of at least substantially
identical
products by different entities. Such a decentralized approach may reduce the
need to deploy
manufacturing equipment and personnel at scale to achieve mass production or
concurrent
production of multiple units. The verification module 102 of the system 100
may reduce
the risk that such a decentralized approach may negatively affect quality
and/or consistency
among products manufactured utilizing the system 100.
Though many industries may deploy and benefit from systems 100 in accordance
with this disclosure, one industry that may deploy and benefit from systems
100 as
disclosed herein may include oil and gas exploration. For example, earth-
boring tools,
cutting elements for earth-boring tools, and equipment and accessories for use
with earth-
CA 03218321 2023- 11- 7
WO 2022/241457
PCT/US2022/072291
- 33 -
boring tools may benefit from specialized materials and manufacturing
processes. Rather
than rely on vertical integration, with a single entity providing personnel,
materials, and
equipment for manufacturing earth-boring tools and related equipment, systems
100
enabling distributed manufacturing may enable customers to access specialized
knowledge
and capabilities without compromising security, quality, or consistency. Other
industries
may likewise benefit from systems 100 in accordance with this disclosure, such
as, for
examples, the automotive, aerospace, power generation, industrial equipment,
construction
equipment, defense, and other industries having specialized manufacturing
needs and high
barriers to deployment.
FIG. 2 is a schematic view of illustrative workflow processes for a product to
be
verified by the system 100 of FIG. 1. For example, the workflows may start
when the
system 100 receives a request for order initiation 202 from a client device,
such as from a
customer or other purchaser of a product through the system 100. At order
initiation 202,
the system 100 may send identifications of product designs available through
the
system 100 to enable a user to select an appropriate product design for
manufacture. The
system 100 may also receive from the user information to assist in presenting
product
designs likely to meet the user's needs, such as, for example, by receiving
expected use
information and/or receiving identification of any existing products to be
replaced.
The system 100 may proceed toward a product selection process 204. For
example,
the system 100 may utilize an assisted design module 206 (e.g., with
artificial intelligence
and/or machine learning) to recommend product designs that may have best
predicted
performance in the received expected uses. When performing order initiation
202 and
product selection process 204, the system 100 may access at least some
portions of a digital
inventory 208 storing the product designs. For example, the system 100 may
utilize one or
more private keys available only to the system 100 to access and decrypt
encrypted data
representative of the product designs in the digital inventory 208. When
providing data
from the digital inventory 208 to a client device to facilitate a product
selection
process 204, the system 100 may limit the data provided to information
sufficient to
identify a given product design (e.g., product name, external images of
product) and
information preapproved by a designer or other rights holder in the product
design for
public disclosure (e.g., marketing information).
Following order acceptance 210, and optionally during order initiation 202 and
the
product selection process 204, the system 100 may update a blockchain 212 to
include a
CA 03218321 2023- 11- 7
WO 2022/241457
PCT/US2022/072291
- 34 -
record of the order. For example, the system 100 may generate an encrypted,
secure
identifier for the product to be manufactured (e.g., a hash), and may store
encrypted data
representative of the product design in the blockchain in a manner associating
the data with
the encrypted, secure identifier. In some examples, the digital inventory 208
may likewise
be maintained on a blockchain 212, such as, for example, a separate blockchain
from the
blockchain 212 for verifying the product.
Upon order acceptance 210 the system 100 may coordinate manufacturing of the
product design, such as, for example, by sending requests for availability to
a
manufacturing marketplace 214 maintained within the system 100. For example,
the
system 100 may contact the manufacturer or manufacturers preferred or required
within the
order to verify the relevant entity or entity's availability and capability to
manufacture the
product in accordance with the order. As another example, the system 100 may
send
information sufficient to identify the product to be manufactured to the
manufacturing
marketplace 214 with a request for manufacturers to confirm availability,
capabilities, and
other willingness to comply with terms of the order. The system 100 may
automatically
coordinate manufacturing among the manufacturers or may send suitable
respondents to a
client device for a customer to approve the manufacturer(s) to manufacture the
product
(e.g., with ratings from prior manufacturing jobs to rank potential
manufacturers).
Once manufacturing has been coordinated via the manufacturing marketplace 214,
the system 100 may transmit confirmation of the order to each approved
manufacturer 216.
The confirmation of the order may include sufficient information to identify
the product to
be manufactured, information regarding any precursors that will be required to
begin
manufacturing, and a request for verification of any manufacturer capabilities
required
before manufacturing can proceed. Following order acceptance 210, each
communication
between the system 100 and each manufacturer relevant to the product may be
verified and
stored in the blockchain 212. For example, all data sent in connection with
transmission of
the order confirmation may be stored in the blockchain 212 in association with
the
encrypted, secure identifier.
Before proceeding to manufacture, the system 100 may require receipt of
verification of precursor materials and/or components 218 from a client device
of the
manufacturer. For example, the system 100 may require receipt of images and/or
digital
records of the source and composition of materials to be utilized during
manufacturing. The
system 100 may also require receipt of images and/or digital records of the
source and
CA 03218321 2023- 11- 7
WO 2022/241457
PCT/US2022/072291
- 35 -
identification of any premade components to be used when manufacturing and/or
assembling the product. Each communication from the manufacturer may be
authenticated,
for example, by the manufacturer's use of a private key put in place during
prequalification
of the manufacturer to participate in the system 100. The system 100 may
update the
blockchain 212 with the data received for verification of precursor materials
and/or
components 218. In some examples, the system 100 may automatically verify the
data
received against terms of the order to authorize further progress toward
fulfilment, or may
send the data received to a client device of the customer to approve progress
within the
system 100.
The system 100 may also require receipt of verification of manufacturer
capabilities 220 from a client device of the manufacturer. For example, the
system 100 may
require receipt of images and/or digital records of the identity and
calibration of
manufacturing devices to be utilized during manufacturing. The system 100 may
also
require receipt of images and/or digital records of certifications and/or
licensing of any
equipment operators of any manufacturing devices to be used when manufacturing
the
product. Each communication from the manufacturer may be authenticated, for
example,
by the manufacturer's use of a private key put in place during
prequalification of the
manufacturer to participate in the system 100. The system 100 may update the
blockchain 212 with the data received for verification of manufacturer
capabilities 220. In
some examples, the system 100 may automatically verify the data received
against terms of
the order to authorize further progress toward fulfilment, or may send the
data received to a
client device of the customer to approve progress within the system 100.
Following verification of precursor materials and/or components 218 and
verification of manufacturer capabilities 220, the system 100 may proceed
toward
coordination and verification of the manufacturing and post-processing process
222. In
some examples, the system 100 may decrypt data from the product design in the
digital
inventory 208 representative of instructions for manufacturing the product
utilizing a
private key accessible to the system 100, may prepare instructions configured
to enable an
automatic manufacturing device (e.g., an additive manufacturing device, a
computer
numerical control (CNC) manufacturing device) to manufacture the product
utilizing the
precursors, and may encrypt and send discrete packets of the instructions to a
connected
client device. The client device may decrypt the packets of instructions,
execute the
instructions to manufacture the product, and send confirmation of deletion of
the packets of
CA 03218321 2023- 11- 7
WO 2022/241457
PCT/US2022/072291
- 36 -
instructions upon completion of each respective packet. In other examples, the
system 100
may decrypt data from the product design in the digital inventory 208
representative of
instructions for manufacturing the product utilizing a private key accessible
to the
system 100, may prepare instructions configured to enable an operator of a
manually
controlled manufacturing device to manufacture the product utilizing the
precursors, and
may encrypt and send the instructions to a connected client device. The
instructions may be
decryptable by the client device, may contain embedded access restrictions to
permit
display of the instructions to manufacture the product, may contain embedded
access
restrictions to prohibit and send attempts to copy, transmit, or otherwise
grant unauthorized
access to or use of the instructions to the system 100, and may contain
embedded access
restrictions to require confirmation of deletion of the instructions upon
confirmation of
completion from the client device.
The system 100 may also require receipt of verification of the manufacturing
process 222 from one or more client devices of the manufacturer. For example,
the
system 100 may require receipt of sensor data generated by sensors oriented
toward the
product, manufacturing device, and/or operator during manufacturing. More
specifically,
the system 100 may require receipt of periodically captured images, a live
video feed, real-
time thermal imaging at a site of manufacturing on the product, real-time
density data of
the product during manufacture, real-time measurements of product dimensions,
or any
combination or subcombination of these and other data indicative of the
process utilized to
manufacture the product and/or the in-manufacture characteristics of the
product. Each
communication from the manufacturer may be authenticated, for example, by the
manufacturer's use of a private key put in place during prequalification of
the manufacturer
to participate in the system 100. The system 100 may update the blockchain 212
with the
data or with an indication representative of the data received for
verification of the
manufacturing process 222. In some examples, the system 100 may automatically
verify
the data received against terms of the order to authorize further progress
toward fulfilment,
or may send the data received to a client device of the customer to approve
progress within
the system 100.
In some examples, the system 100 may decrypt data from the product design in
the
digital inventory 208 representative of instructions for post-processing the
product utilizing
a private key accessible to the system 100, may prepare instructions
configured to enable
an automatic post-processing device (e.g., a computer-controlled heat
treatment device, a

computer-controlled surface treatment device) to process the product, and may
encrypt and
send discrete packets of the instructions to a connected client device upon
receiving
confirmation that the product is available and ready for post-processing. The
client device
may decrypt the packets of instructions, execute the instructions to process
the product, and
send confirmation of deletion of the packets of instructions upon completion
of each
respective packet. In other examples, the system 100 may decrypt data from the
product
design in the digital inventory 208 representative of instructions for
processing the product
utilizing a private key accessible to the system 100, may prepare instructions
configured to
enable an operator of a manually controlled post-processing device to process
the product,
and may encrypt and send the instructions to a connected client device. The
instructions
may be decryptable by the client device, may contain embedded access
restrictions to
permit display of the instructions to process the product, may contain
embedded access
restrictions to prohibit and send attempts to copy, transmit, or otherwise
grant unauthorized
access to or use of the instructions to the system 100, and may contain
embedded access
restrictions to require confirmation of deletion of the instructions upon
confirmation of
completion from the client device.
The system 100 may also require receipt of verification of the post-processing
process 222 from one or more client devices of the post-processor. For
example, the
system 100 may require receipt of sensor data generated by sensors oriented
toward the
product, post-processing device, and/or operator during post-processing. More
specifically,
the system 100 may require receipt of periodically captured images, a live
video feed, real-
time thermal imaging at a site of post-processing on, or an entirety of, the
product, real-
time density data of the product during post-processing, real-time
measurements of product
dimensions, or any combination or subcombination of these and other data
indicative of the
process utilized to process the product and/or the in-process characteristics
of the product.
Each communication from the post-processor may be authenticated, for example,
by the
post-processor's use of a private key put in place during prequalification of
the post-
processor to participate in the system 100. The system 100 may update the
blockchain 212
with the data or with an indication representative of the data received for
verification of the
post-processing process 222. In some examples, the system 100 may
automatically verify
the data received against terms of the order to authorize further progress
toward fulfilment,
or may send the data received to a client device of the customer to approve
progress within
the system 100.

PCT/US2022/072291
- 38 -
The system 100 may also be configured to accept verification of inspection
processes 224 and final product characteristics. For example, the system 100
may decrypt
data from the product design in the digital inventory 208 representative of
product
characteristics to be verified upon completion of manufacturing and post-
processing the
product utilizing a private key accessible to the system 100, may prepare
instructions
configured to enable an automatic inspection device (e.g., a CT scanner) to
inspect the
product, and may encrypt and send discrete packets of the instructions to a
connected client
device upon receiving confirmation that the product is available and ready for
final
inspection. The client device may decrypt the packets of instructions, execute
the
instructions to inspect the product, and send confirmation of deletion of the
packets of
instructions upon completion of each respective packet. In other examples, the
system 100
may decrypt data from the product design in the digital inventory 208
representative of
instructions for inspecting the product utilizing a private key accessible to
the system 100,
may prepare instructions configured to enable an operator of a manually
controlled
inspection device or manually operated inspection tools (e.g., calipers for
measuring
dimensions) to inspect the product, and may encrypt and send the instructions
to a
connected client device. The instructions may be decryptable by the client
device, may
contain embedded access restrictions to permit display of the instructions to
inspect the
product, may contain embedded access restrictions to prohibit and send
attempts to copy,
transmit, or otherwise grant unauthorized access to or use of the instructions
to the
system 100, and may contain embedded access restrictions to require
confirmation of
deletion of the instructions upon confirmation of completion from the client
device.
The system 100 may also require receipt of the verification of inspection
processes 224 and results from one or more client devices of the inspector.
For example,
the system 100 may require receipt of sensor data generated by sensors
oriented toward the
product, inspection device, and/or inspector during post-processing. More
specifically, the
system 100 may require receipt of periodically captured images, a live video
feed, real-time
or post-scan imaging of the product and its interior structure and material
composition from
a scanner (e.g., a CT scanner), real-time or post-detection measurements of
product
dimensions, or any combination or subcombination of these and other data
indicative of the
process utilized to inspect the product and/or the final characteristics of
the product. Each
communication from the inspector may be authenticated, for example, by the
inspector's
use of a private key put in place during prequalifi cation of the inspector to
participate in the
CA 03218321 2023- 11- 7
WO 2022/241457
PCT/US2022/072291
- 39 -
system 100. The system 100 may update the blockchain 212 with the data or with
an
indication representative of the data received for verification of inspection
processes 224
and results. In some examples, the system 100 may automatically verify the
data received
against terms of the order to authorize further progress toward fulfilment, or
may send the
data received to a client device of the customer to approve progress within
the system 100.
In some examples, the system 100 may be configured to coordinate delivery
logistics 226 for the product. For example, upon acceptance of the product
following
manufacturing, post-processing, and inspection, the system 100 may send a
request to a
delivery service provider to provide a quote for delivery costs or to pick up
the product
from the inspector or another temporary possessor of the product for delivery.
The system 100 may be configured to receive confirmation of order fulfillment
228.
For example, verification of order fulfillment 228 may be received from a
delivery service
provider upon delivery of the product or from a customer upon receipt of the
product.
When order fulfillment 228 has been verified, the system 100 may verify and
encrypt the
record of manufacturing of the product in the blockchain 212. For example, the
data
received, or data representative of the data received, from order initiation
202 through
order fulfillment 228 may be encrypted and uploaded to the blockchain 212 in a
manner
associating the data with the encrypted, secure identifier. The record may be
immutable, or
may only be changeable with consensus from relevant participants in the system
100,
ensuring that the data is available and reliable for interested parties, such
as, for example,
the customer, auditors, and regulators.
In some examples, a physical inventory manager 230 may be updated to reflect
delivery and ownership of the product upon order fulfillment 228. The physical
inventory
manager 230 may enable the system 100 to track inventory and stock, and may
enable the
system 100 to facilitate reordering or replacement of the product responsive
to trends
and/or status of the physical inventory reflected in the physical inventory
manager 230.
In some examples, the system 100 may be configured to receive verification of
usage and wear 232 resulting from in-field use of' the product. For example,
the system 100
may be configured to receive data representative of the location, system into
which the
product is integrated, operational parameters used in-field, data
representative of product
performance in the field, data representative of measurements of product
dimensions due to
in-field wear, or any combination or subcombination of these and other data
indicative of
the usage and wear of the product and/or the final characteristics of the
product. Each

communication from the owner or operator may be authenticated, for example, by
the
owner or operator's use of a private key put in place during prequalification
of the owner or
operator to participate in the system 100. The system 100 may update the
blockchain 212
with the data or with an indication representative of the data received for
verification of
usage and wear 232. The verification of usage and wear 232 may enable the
system 100 to
track product performance and suitability for use, and may enable the system
100 to
facilitate reordering or replacement of the product responsive to trends
and/or status of the
product's characteristics and performance. In some examples, the system 100
may be
configured to receive and store in the blockchain 212 data representative of
repair,
refurbishment, and maintenance of the product, in a manner similar to the
verification of
usage and wear 232.
FIG. 3 is a flowchart of a method 300 of providing end-to-end verification of
workflow processes for a product. The method 300 may involve, for example,
initiating an
order and generating an encrypted, secure identifier for the product, as
indicated at act 302.
More specifically, a request from a client device may be received to initiate
an order, and
information to assist in selecting an appropriate product may be requested. In
some
examples, requests for the information may be sent to the client device, such
as, for
example, utilizing a webform. In some examples, the encrypted, secure
identifier may be
generated upon order initiation, enabling tracking of the ordering process. In
other
examples, the encrypted, secure identifier may be generated after an order is
confirmed, as
set forth below.
In some examples, the method 300 may involve performing assisted product
selection, as indicated at act 304. For example, a digital inventory of
available product
designs may be searched, and product designs having best recorded performance
in use
cases closest to expected uses received from a client device may be
recommended. In some
examples, the method 300 may also involve performing assisted product design.
For
example, a designer or other rights holder in a product design may enable
alterations to be
made a product design in the digital inventory within pre-approved limits
(e.g., changes to
size, shape, dimensions, alternative materials, alternative manufacturing
processes). As
another example, potential alterations to a product design may be recommended
by the
system by analyzing performance of the product against features of other,
similar products
enabling improved performance.
CA 03218321 2023- 11- 7
WO 2022/241457
PCT/US2022/072291
- 41 -
The method 300 may involve accepting selection of a product from the digital
inventory, as indicated at act 306, and finalizing the product design to be
manufactured, as
indicated at act 308. Upon finalization of the product design to be
manufactured, a digital
twin of the product, including the product design, may be created and a
blockchain may be
updated to associate data, such as the product design and digital twin, with
the encrypted,
secure identifier utilizing a secure, distributed transaction ledger, as
indicated at act 324.
The method 300 may proceed to begin transmitting manufacturing instructions
for
manufacturing the product to a manufacturer, as indicated at act 310. For
example,
information sufficient to identify the product and to enable the manufacturer
to obtain any
necessary precursors and equipment may be transmitted. The method 300 may
involve
receiving pre-manufacturing verification of requested and/or required
information, such as,
for example, precursor availability and manufacturer capabilities, as
indicated at act 312.
Upon receipt of the pre-manufacturing verification, the blockchain may be
updated to
associate the pre-manufacturing verification with the encrypted, secure
identifier utilizing a
secure, distributed transaction ledger, as indicated at act 324.
The method 300 may proceed to receive in-process manufacturing verification,
as
indicated at act 314. For example, operational parameters used and resulting
product
characteristics produced during manufacturing may be received. Upon receipt of
the in-
process manufacturing verification, the blockchain may be updated to associate
the in-
process manufacturing verification with the encrypted, secure identifier
utilizing a secure,
distributed transaction ledger, as indicated at act 324.
The method 300 may proceed to receive verification of post-processing
performed
on the product, as indicated at act 316. For example, operational parameters
used and
resulting product characteristics produced during post-processing may be
received. Upon
receipt of the post-processing verification, the blockchain may be updated to
associate the
post-processing verification with the encrypted, secure identifier utilizing a
secure,
distributed transaction ledger, as indicated at act 324.
The method 300 may proceed to receive verification of product characteristics,
as
indicated at act 318. For example, data representative of final product
characteristics
resulting from manufacturing and post-processing may be received. Upon receipt
of the
verification of product characteristics, the blockchain may be updated to
associate the
verification of product characteristics with the encrypted, secure identifier
utilizing a
secure, distributed transaction ledger, as indicated at act 324.

In some examples, the method 300 may involve fulfilling the order, as
indicated at
act 320. For example, the product meeting the requirements of the product
design selected
when finalizing the product design at act 308 may be shipped and delivered to
the
purchaser. In some examples, the method 300 may involve receiving verification
of use,
maintenance, refurbishment, and other post-manufacture data (e.g., repair,
retirement), as
indicated at act 322.
FIG. 4 is a flowchart of another method 400 of providing end-to-end
verification of
workflow processes for a product. The method 400 may involve, for example,
generating
an encrypted, secure identifier, as indicated at act 402, the encrypted,
secure identifier
configured to collect and associate the verification received in a secure,
reliable database.
For example, the method 400 may involve generating a hash or token for use in
a
blockchain to serve as the encrypted, secure identifier.
Following or concurrent with generation, the method 400 may involve updating a
blockchain to store the encrypted, secure identifier utilizing a secure,
distributed
transaction ledger, as indicated at act 404. For example, a block for storing
the workflow
verification may be created and linked to a previous block in the blockchain
utilizing the
encrypted, secure identifier.
In some examples, the method 400 may involve maintaining verification data
representative of the workflow processes in association with the encrypted,
secure
identifier in different, interlinked blocks of the blockchain, as indicated at
act 412. In other
examples, the method 400 may involve maintaining verification data
representative of the
workflow processes in association with the encrypted, secure identifier in a
single,
dedicated block of the blockchain, as indicated at act 406. In other examples,
the
method 400 may involve maintaining verification data representative of the
workflow
processes in association with the encrypted, secure identifier in a different,
interlinked
blockchains, as indicated at act 414.
In some examples, the method 400 may involve updating the blockchain in real
time to associate at least some verification data with the encrypted, secure
identifier
utilizing the secure, distributed transaction ledger, as indicated at act 408.
For example, the
blockchain may be updated within 1 minute, 1 second, 10 cycles, or 1 cycle of
receipt of
the verification data to provide real-time updates of workflow verification in
the
blockchain.
CA 03218321 2023- 11- 7
WO 2022/241457
PCT/US2022/072291
- 43 -
In some examples, the method 400 may involve updating the blockchain after
completion of a process to associate at least some verification data with the
encrypted,
secure identifier utilizing the secure, distributed transaction ledger, as
indicated at act 410.
For example, the verification data may be collected in real time, compared to
terms, and the
blockchain updated with the results of the comparison. As another example, the
verification
data may be collected in real time and the blockchain may be updated to
include the
verification data only after all the verification data has been received. As
yet another
example, the verification data may only be received after all the verification
data has been
generated, and the blockchain may be updated to include the verification data
or an
indication representative of the verification data.
In some examples, the blockchain may be updated with certain of the
verification
data in real time and a remainder of the verification data upon receipt of the
relevant
portion of the remainder of the verification data. In other examples, updates
to the
blockchain may consistently be made in real time or upon receipt of a complete
portion of
the verification data.
FIG. 5 is a flowchart of another method 500 of providing end-to-end
verification of
workflow processes for a product. The method 500 may involve, for example,
accepting
pre-manufacture verification of manufacturer capabilities and product
precursors for a
product to be additively manufactured, as indicated at act 502. For example, a
server
hosting a system for providing verification of product workflows may prompt a
client
device of an additive manufacturer to send the verification of manufacturer
capabilities and
product precursors, and may not proceed toward additively manufacturing the
product until
after receipt of the verification of manufacturer capabilities and product
precursors. More
specifically, the system may accept the pre-manufacture verification of the
manufacturer
capabilities by receiving images of quality required documentation (e.g.,
operator
licensing/certification, machine identity, machine calibration). As another
more specific
example, the system may accept the pre-manufacture verification of the
precursors for
manufacturing the product by receiving images of the materials and components
to be used
to additively manufacture the product or digital specification sheets for the
sourcing,
material composition, and identification of the materials and components to be
used to
additively manufacture the product. As a specific, nonlimiting example,
acceptance of the
pre-manufacture verification of the product precursors may be accomplished by
accepting
pre-manufacture verification of materi al compositi on, particle size
distribution, density,
CA 03218321 2023- 11- 7
WO 2022/241457
PCT/US2022/072291
- 44 -
morphology, flow properties, or any combination of these properties of the
product
precursors. Following receipt of the pre-manufacture verification of
manufacturer
capabilities and product precursors, the method 500 may involve updating the
blockchain
to associate the pre-manufacture verification of manufacturer capabilities and
product
precursors with an encrypted, secure identifier for the product to be
manufactured utilizing
a secure, distributed transaction ledger, as indicated in act 504.
In some examples, the system may accept measures of environmental impact
associated with sourcing and manufacturing the product and update the
blockchain to
associate the measures of environmental impact with the encrypted, secure
identifier
utilizing the secure, distributed transaction ledger. For example, the system
may accept
indication of whether precursor materials and/or components are recycled from
a previous
product, a measure of green-house gas emissions from sourcing the precursors,
an
indication whether the precursors are from a renewable source, an indication
how the
precursors may be reused or recycled upon retirement of the product, or any
combination
or subcombination of these or other indications of environmental impact.
The method 500 may involve generating discrete packets of operational
parameters
to enable an additive manufacturing device to manufacture the product, as
indicated at
act 506. For example, each packet may include operational parameters to enable
the
additive manufacturing device to manufacture a respective portion of the
product, as also
indicated at act 506. More specifically, the method 500 may involve remotely
controlling
an additive manufacturing process and machine utilizing instructions generated
at a remote
server from a product file only accessible in whole utilizing the remote
server. In some
examples, the network-connected additive manufacturing device may be
configured a
selective laser sintering 3D printing device, and the discrete packets of
operational
parameters may be generated by generating discrete packets of operational
parameters
including atmospheric gas flow rate, oxygen content of atmospheric gas,
thermal
management, laser power, laser focus, laser travel speed, laser alignment, or
any
combination of these operational parameters of the network-connected additive
manufacturing device.
The method 500 may involve encrypting and sending operational parameters to
enable a network-connected additive manufacturing device to manufacture the
product, as
indicated at act 508. For example, the operational parameters may be sent for
manufacturing as discrete packets, with at least one packet being sent after
receipt of
CA 03218321 2023- 11- 7
WO 2022/241457
PCT/US2022/072291
- 45 -
confirmation that at least another previous packet is complete and associated
operational
parameters for the at least another previous packet have been deleted, as also
indicated at
act 508. When sending subsequent packets, a time from completion of the
respective
previous packet may be sufficient to ensure that another respective portion of
the product to
be manufactured responsive to execution of the subsequent packet may begin
without
interruption in an additive manufacturing process. More specifically, an
initial set of
packets of operational parameters sent to the additive manufacturing device
may include
sufficient operational parameters that operational parameters in a first
packet can be
completed, manufacturing can continue uninterrupted, confirmation of
completion and
deletion of the first packet can be received, and subsequent packets may be
sent and
received, again without interrupting manufacturing and without the
manufacturing device
having access to sufficient operational parameters to manufacture the entire
product at a
tune.
Transmission of the operational parameters may be achieved by, for example, a
server hosting a system for providing end-to-end verification sending
encrypted packets of
the operational parameters to a client device (e.g., a network-connected
additive
manufacturing device, a network-connected CNC manufacturing device). The
client device
may have a private key enabling the client device to decrypt and utilize the
operational
parameters to manufacture the product (e.g., as a result of a prequalification
process). The
packets may also include instructions causing the client device to delete the
operational
parameters and other data in a given packet following execution. The packets
may further
include access restrictions configured to report unauthorized access of the
operational
parameters by devices other than the authorized client device or access and
use by the
client device beyond expected access and use. By separating the manufacturing
instructions
into discrete packets, tracking access and use, and optionally pre-qualifying
participants in
the system, risks of copying, reverse-engineering, and the manufacture of
unauthorized
products may be reduced. The method 500 may then involve updating the
blockchain to
associate the operational parameters with the encrypted, secure identifier
utilizing the
secure, distributed transaction ledger, in some examples.
In some examples, the method 500 may involve, for example, tailoring the
operational parameters to cause the additive manufacturing device to produce a
unique
physical characteristic of the product associated with the encrypted, secure
identifier before
sending the operational parameters to the additive manufacturing device. For
example, one
CA 03218321 2023- 11- 7
WO 2022/241457
PCT/US2022/072291
- 46 -
or more of the packets may contain instructions that, when executed, cause the
manufacturing device to produce a detectable, unique variation in product
characteristics
(e.g., a serial number on the product, a randomized variation in post-
manufacture product
characteristics, an impurity implanted in a material of the product, some
combination of
these unique physical characteristics associated with the encrypted, secure
identifier) while
manufacturing the product.
In some examples, the method 500 may involve requiring receipt of another
encrypted, secure identifier from the network-connected additive manufacturing
device
before sending the respective packets of operational parameters. The other
encrypted,
secure identifier may be indicative that the network-connected additive
manufacturing
device is preauthorized to manufacture product designs within a digital
inventory of
product designs, including the product design for the product.
The method 500 may further involve accepting in-manufacture verification of
the
operational parameters utilized by the additive manufacturing device when
manufacturing
the product, as indicated at act 510. For example, the packets sent to the
client device may
further include instructions that, when executed, cause the client device to
send
confirmation of the actual operational parameters utilized by the client
device. The
method 500 may then proceed with updating the blockchain to associate the in-
manufacture
verification of the operational parameters with the encrypted, secure
identifier utilizing the
secure, distributed transaction ledger, as indicated at act 512. Creating a
secure, verified
record of the instructions sent and the actual operational parameters used
when
manufacturing the product, tied to the chain of other verification for the
product, may
provide a reliable record regarding workflows utilized when manufacturing the
product.
In some examples, the method 500 may involve accepting in-manufacture
verification of a product characteristic for a portion of the product
manufactured by the
additive manufacturing device. For example, data generated by one or more
sensors
oriented and positioned to detect one or more characteristics of the product
during
manufacturing may be received. More specifically, the in-manufacture
verification of the
product characteristic for the portion of the product manufactured by the
network-
connected additive manufacturing device may be accepted from, for example, an
image
sensor, a heat sensor, a sound sensor, or any combination of these positioned
and oriented
to automatically detect the product characteristic. Upon or after receipt, the
blockchain may
CA 03218321 2023- 11- 7
WO 2022/241457
PCT/US2022/072291
- 47 -
be updated to associate the in-manufacture verification of the product
characteristic with
the encrypted, secure identifier utilizing the secure, distributed transaction
ledger.
In some examples, the method 500 may involve stopping sending the operational
parameters to the additive manufacturing device when the in-manufacture
verification of
the product characteristic is outside a predetermined threshold. For example,
the system
may automatically pause or stop manufacturing when received verification of
one or more
product characteristics is outside specification, outside tolerances, or
otherwise inconsistent
with the product design or terms of the order. More specifically, the method
500 may
involve, for example, pausing sending the operational parameters to the
additive
manufacturing device when the in-manufacture verification of the product
characteristic is
within the predetermined threshold and outside another, smaller threshold
(e.g., when one
or more product characteristics is within purchaser specification but outside
designer-
preferred tolerances). When manufacturing is merely paused, the system may
require
confirmation of acceptance from a purchaser before resuming sending the
operational
parameters to the additive manufacturing device. Upon or after receipt, the
blockchain may
be updated to associate an indication that the in-manufacture verification of
the product
characteristic was outside the predetermined threshold with the encrypted,
secure identifier
utilizing the secure, distributed transaction ledger.
In some examples, the system may automatically request funds from a payment
account when the in-manufacture verification of the product characteristic is
within a
predetermined threshold. For example, when each product characteristic is
within all
specified thresholds (e.g., is within purchaser specification and within
designer-preferred
tolerances), the system may automatically execute a smart contract utilizing
the secure,
distributed transaction ledger to cause purchaser funds to be released to the
manufacturer
responsive to verified completion of manufacturing in accordance with the
order. More
specifically, the system may record intellectual property rights associated
with the product,
the product file, the product precursors, or any combination of these stored
in a database
accessible to the processor, update the blockchain to associate the
intellectual property
rights with the encrypted, secure identifier utilizing the secure, distributed
transaction
ledge, and generate an account of royalties due for the product, the product
file, the product
precursors, or any combination of these.
In some examples, the method 500 may involve accepting post-manufacture
verification of operational parameters for post-manufacture processing
performed on the
CA 03218321 2023- 11- 7
WO 2022/241457
PCT/US2022/072291
- 48 -
product, post-manufacture product characteristics for the product, or both. In
some such
examples, acceptance of the in-manufacture verification of the operational
parameters
utilized by the additive manufacturing device when manufacturing the product
may be
accomplished by accepting an indication that all the operational parameters
utilized by the
additive manufacturing device when manufacturing the product were within a
specified
threshold. More specifically, acceptance of the in-manufacture verification of
the
operational parameters utilized by the additive manufacturing device when
manufacturing
the product may involve, for example, receiving a log of at least
substantially all the
operational parameters utilized by the additive manufacturing device when
manufacturing
the product. As a specific, nonlimiting example, the system may accept the in-
manufacture
verification of the operational parameters utilized by the additive
manufacturing device
when manufacturing the product by receiving the log in real time from a
network-
connected additive manufacturing device while the network-connected additive
manufacturing device manufactures the product. As another example, acceptance
of the in-
manufacture verification of the post-manufacture product characteristics for
the product
may involve accepting post-manufacture RT metrology, tensile strength,
Rockwell
hardness, microstructure, density, porosity, impact toughness, or any
combination of these
characteristics of the product. More specifically, acceptance of the in-
manufacture
verification of the post-manufacture product characteristics for the product
may involve,
for example, receiving scan data from a computed tomography scanner positioned
and
oriented to automatically detect the post-manufacture product characteristics.
Upon receipt
of the post-manufacture verification of operational parameters for post-
manufacture
processing performed on the product, post-manufacture product characteristics
for the
product, or both, the system may update the blockchain to associate the post-
manufacture
verification of the operational parameters for the post-manufacture processing
performed
on the product, the post-manufacture product characteristics for the product,
or both with
the encrypted, secure identifier utilizing the secure, distributed transaction
ledger.
FIG. 6 is a schematic of a network 600 for implementing end-to-end
verification of
workflow processes. The network 600 may include, for example, at least one
first
server 602 configured to host at least some modules for administering a system
for
verifying end-to-end workflows of a product. For example, the first server 602
or first
grouping of servers 602 may host software including an ordering module, an API
for
interfacing with a physical inventory module, a digital inventory module, a
design selection

assistance module, a manufacturing module, an API for interfacing with an
order
fulfillment module, an API for receiving input from a use and wear input
module, and an
API for receiving input from a repair and refurbishment module, as described
previously in
connection with FIG. 1. The first server 602 or first grouping of servers 602
may be
connected to a network 604 to enable communication for administration of the
system. For
example, the first server 602 or first grouping of servers 602 may be
connected to a local
area network (LAN), a wide area network (WAN), or the Internet.
In some examples, the network 600 may include additional servers or additional
groupings of servers dedicated to store data usable by the system or to
administer certain
modules of the system. For example, the network 600 may include a second
server 606 or a
second grouping of servers 606 configured to administer and store or host a
node of the
blockchain for containing the verification of the end-to-end workflows for the
product.
The second server 606 or second grouping of servers 606 may be publicly
accessible in some examples, though the data stored in the second server 606
or second
grouping of servers 606 may be encrypted, requiring a user to have one or more
private
keys to decrypt the data. For example, some users may have private keys
enabling
decryption of only those portions of the blockchain (e.g., blocks, portions of
blocks) for
which the user has prequalified access. More specifically, the blockchain may
be encrypted
utilizing multiple encryption (also called "cascade encryption," "cascade
ciphering," and
-superencipherment"), with all users hosting nodes of the blockchain having
private keys
to decrypt a first layer of encryption, granting access to any single-
encrypted data, and only
certain users having private keys to fully decrypt all layers of encryption of
a given set or
subset of data. As a specific, nonlimiting example, approval from respective
administrators
may be required to enable an entity to fully decrypt all layers of encryption.
In such an
example, approval from each designer or other rights holder in a product
design may be
required to decrypt data representative of the product design and instructions
for
manufacturing the product design; approval from the manufacturer of a product
may be
required to decrypt data representative of the manufacturing processes (e.g.,
actual
operational parameters) used during manufacturing; approval from the post-
processor of a
product may be required to decrypt data representative of the post-processing
(e.g., actual
operational parameters) performed on the product. In some such examples, a
customer,
purchaser, or other owner of a product may be pre-approved to fully decrypt
all data
verifying the workflows for the product

In some examples, the second server 606 or second grouping of servers 606 may
be
distinct from the first server 602 or first grouping of servers 602. In other
examples, the
second server 606 or second grouping of servers 606 may be integrated with or
the same as
the first server 602 or first grouping of servers 602.
In some examples, the network 600 may include a third server 608 or a third
grouping of servers 608 configured to administer an API to access, or to
administer and
store or host a node of another blockchain for containing, the digital
inventory. The third
server 608 or third grouping of servers 608 may not be publicly accessible,
and the data
stored in the third server 608 or third grouping of servers 608 may be
encrypted, requiring
a user to have one or more private keys to decrypt the data, as discussed
previously in
connection with the second server 606 or second grouping of servers 606. In
some
examples, the third server 608 or third grouping of servers 608 may be
distinct from the
first server 602 or first grouping of servers 602 and/or the second server 606
or second
grouping of servers 606. In other examples, the third server 608 or third
grouping of
servers 608 may be integrated with or the same as the first server 602 or
first grouping of
servers 602, the second server 606 or second grouping of servers 606, or both.
In some examples, the network 600 may include a fourth server 610 or a fourth
grouping of servers 610 configured to administer an API to access, or to
administer and
store or host a node of yet another blockchain for containing, data
representative of
physical inventory (e.g., of customers, precursor suppliers, manufacturers,
post-
processors). The fourth server 610 or fourth grouping of servers 610 may not
be publicly
accessible, and the data stored in the fourth server 610 or fourth grouping of
servers 610
may be encrypted, requiring a user to have one or more private keys to decrypt
the data, as
discussed previously in connection with the second server 606 or second
grouping of
servers 606. In some examples, the fourth server 610 or fourth grouping of
servers 610 may
be distinct from the first server 602 or first grouping of servers 602, the
second server 606
or second grouping of servers 606, and/or the third server 608 or third
grouping of
servers 608. In other examples, the fourth server 610 or fourth grouping of
servers 610 may
be integrated with or the same as the first server 602 or first grouping of
servers 602, the
second server 606 or second grouping of servers 606, the third server 608 or
third grouping
of servers 608, or any combination or subcombination of these.
In some examples, the network 600 may include a fifth server 612 or a fifth
grouping of servers 612 configured to administer an API to access, or to
administer and

store or host a node of still another blockchain for containing, a database of
keys required
to encrypt and decrypt the data handled by the system. The fifth server 612 or
fifth
grouping of servers 612 may only be accessible to the system, and other users
of the system
may be required to maintain a separate database of their own keys for
interacting with the
system in some embodiments. In other embodiments, the fifth server 612 or
fifth grouping
of servers 612 may only be accessible to pre-authenticated users of the system
with access
restrictions enabling a user to only access those keys which the pre-
authenticated user is
authorized to utilize. In some examples, the fifth server 612 or fifth
grouping of servers 612
may be distinct from the first server 602 or first grouping of servers 602,
the second
server 606 or second grouping of servers 606, the third server 608 or third
grouping of
servers 608, and/or the fourth server 610 or the fourth grouping of servers
610. In other
examples, the fifth server 612 or fifth grouping of servers 612 may be
integrated with or
the same as the first server 602 or first grouping of servers 602, the second
server 606 Or
second grouping of servers 606, the third server 608 or third grouping of
servers 608, the
fourth server 610 or fourth grouping of servers 610, or any combination or
subcombination
of these.
The network 600 may be accessible to one or more client devices. For example,
a
client device 614 of a customer, a client device 616 of a designer or other
rights holder in a
product design, a client device 618 of a manufacturer, and/or a client device
620 of another
entity authorized to participate in the system (e.g., a precursor provider, a
post-processor, a
delivery service provider, an auditor, a regulator, a system administrator)
may access the
system via the network 604. More specifically, the first server 602 or first
grouping of
servers 602 may deliver data to the respective client device 614 through 620
from the
respective other servers 606 through 612 or other groupings of servers 606
through 612, the
data being unencrypted and in at least some instances re-encrypted by the
system on the
first server 602 or first groupings of servers 602 before sending to the
respective client
device 614 through 620. The servers and client devices may be configured as
network-
connectable computer systems, as described in greater detail in connection
with FIG. 7, or
other network-connectable devices (e.g., network-connected manufacturing
devices).
FIG. 7 is a schematic of a computer system 700 for connection to the network
of
FIG. 6. The computer system 700 may include, for example, at least one
processor 702
configured to execute software programs containing computing instructions. The
processor 702 may be configured to execute a wide variety of operating systems
and
CA 03218321 2023- 11- 7
WO 2022/241457
PCT/US2022/072291

applications including the computing instructions for administering systems
and
subsystems in accordance with this disclosure. The processor 702 may be
configured as,
for example, a microprocessor, controller, microcontroller, or state machine
suitable for
carrying out processes of the present disclosure. The processor 702 may also
be
implemented as a combination of computing devices, such as a combination of a
DSP and a
microprocessor, a plurality of microprocessors, one or more microprocessors in
conjunction with a DSP core, or any other such configuration.
The computer system 700 may also include at least one memory device 704
configured to hold computing instructions, data, and other information for
performing a
wide variety of tasks including administering systems and subsystems of the
present
disclosure. By way of example, and not limitation, the memory device 704 may
include
Synchronous Random Access Memory (SRAM), Dynamic RAM (DRAM), Read-Only
Memory (ROM), Flash memory, and the like.
The computer system 700 may further include at least one storage device 706
configured to store relatively large amounts of nonvolatile information for
use in the
computer system 700. By way of example and not limitation, the storage device
706 may
include computer-readable media (CRM). This CRM may include, but is not
limited to,
magnetic and optical storage devices such as disk drives, magnetic tape, CDs
(compact
discs), DVDs (digital versatile discs or digital video discs), and
semiconductor devices
such as RAM, DRAM, ROM, EPROM, Flash memory, and other equivalent storage
devices. "Computer readable media," as utilized herein, excludes transitory
signals.
The processor 702, memory device 704, and storage device 706 may be
interconnected to one another utilizing a bus 708. A person of ordinary skill
in the art will
recognize that the computer system 700 may be configured in many different
ways with
different types of interconnecting buses between the various elements.
Moreover, the
various elements may be subdivided physically, functionally, or a combination
thereof As
one nonlimiting example, the memory device 704 may be divided into cache
memory,
graphics memory, and main memory. Each of these memories may communicate
directly
or indirectly with the processor 702 on separate buses, partially combined
buses, or a
common bus.
A networking card 710 may be connected to the remainder of the computer
system 700 via the bus 708. The networking card 710 may be configured for
communicating with other devices or communication networks. As nonlimiting
examples,
CA 03218321 2023- 11- 7
WO 2022/241457
PCT/US2022/072291
- 53 -
the networking card 710 may include elements for communicating on wired and
wireless
communication media, such as for example, serial ports, parallel ports,
Ethernet
connections, universal serial bus (USB) connections, IEEE 1394 (-firewire-)
connections,
ThunderboltTm connections, BLUETOOTH wireless networks, ZIGBEE wireless
networks, 502.11 type wireless networks, cellular telephone/data networks, and
other
suitable communication interfaces and protocols.
In some examples, such as when the computer system 700 is configured as a
client
device, the computer system 700 may include one or more input devices 712
configured to
receive user input. As specific, nonlimiting examples, the input devices 712
may include a
keyboard 714 and mouse 716, though other input devices 712 may include image
sensors,
microphones, trackballs, macropads, and other input devices 712 known in the
art.
In some examples, such as when the computer system 700 is configured as a
client
device, the computer system 700 may include one or more output devices 718
configured
to provide output. As specific, nonlimiting examples, the output devices 718
may include a
monitor 720; though other output devices 718 may include audio drivers and
other output
devices 718 known in the art.
Systems in accordance with this disclosure may enable secure, decentralized
manufacturing of products. Workflows executed when performing the secure,
decentralized
manufacturing may be captured and reflected in a secure database for verifying
the
workflows. For example, building the system on a blockchain backbone may
ensure that
the provenance of products is verifiable, reducing the risk of black and grey
market
products circulating from the system. In addition, implementing the system
with
blockchain technology and encryption protocols, including multi-layered
encryption in at
least some instances, may reduce the risk that unauthorized products will be
manufactured
in the first place.
Repeatable, verified manufacturing of products may also realize downstream
benefits. For example, a customer wishing to audit a manufacturer's
capabilities,
equipment, calibration, and performance may turn to the verified record of
workflows,
rather than sending an auditor to inspect the manufacturer's facilities. In
addition, a
regulator wishing to verify whether a product is compliant with relevant
government
standards may consult the verified record of workflows to receive a verified
record of the
product's sourcing, manufacturing, and characteristics.
